Why Do Castles Have Moats?

The word ‘moat’ originated from its French version ‘motte’, meaning a mound or hillock. In contemporary times a moat is regarded as a deep, broad ditch that is dug around castles. There are so many intriguing facts surrounding castles, one of which is moats, raising questions: Why on earth did castles have moats?

Castles have moats because they were a part of its intricate defence system. Additionally, moats served as a go-to reserve against famine/ or hard times. Finally, history tells us that moats protected castles against the attack and may have served as ponds where seafood was reared; or as a source of sand/ earth for building tall walls.

So, as you can see, castle moats were very important; Some ditches were filled with water, while others were left dry. 

In this article, we explored the common uses of castle moats throughout their history’s timeline so we could answer all your questions regarding the castle moat. 

So read on and let us know what you think in the comment section.

The History of Castles and moats

It is impossible to talk about castle moats without addressing the nature of assaults that castles faced at the time. 

In the medieval era, kings and nobles built castle moats for defence purposes in the following ways:

1. To prevent penetration into the castle: Since ancestors built moats roundabout castles, assailants could not wage war on the castle without mounting a bridge or moving their equipment over the ditch. 

While the attackers planted their bridges, the castle security could easily spot them and prepare for the attack in advance.

2. To prevent an underground assault: Moats protected castles by preventing attackers from digging underground tunnels to the bottom of the castles and attacking from there. 

In the medieval era, one of the significant ways to bring down a castle gate was to burn it underground. 

So, castles that had moats filled with water had nothing to worry about in that regard because every hole dug would be filled with water.

3. To prevent the movement of assault weapons: Castles were fortified, but so also were the weapons created to bring them down. 

Examples of such weapons are the siege towers and battering rams, both made of wood. Such heavy merchandise could not be carried or transported over the moats, reducing attacks from such destabilizing weapons.

In more recent times, we can see moats used for warfare, decoration, and design and defence mechanisms but these latter moats were not necessarily attached to a castle.

How were moats made?

Engineers mostly built castle moats manually. Since they were made for a purpose, the sizes and depths of ditches varied. 

The builders were digging holes as far, as wide, and as deep as they wanted. Also, at the time, there were limited building tools, so manpower played a huge role. 

Sometimes, castle owners filled moats with water, and other times, they diverted lakes into the moat, and they were left bare in some cases. 

As time progressed, the idea behind moats led to water as a defence mechanism, as shown in the Bodiam Castle of 1385, built on an artificial lake. 

In parts of Africa and Asia, moats were dug, and the sand/ earth gotten from them was used to build tall walls to protect cities, communities, or castles, as the case may be. Where such a moat are filled with water, the city is near to impenetrable. 

Lastly, on this note, some moats were natural, but most often than not, they were not castle moats (because obviously, nature didn’t consult castle owners before turning an area into a moat). 

Natural moats were often swarmed with water during a flood in early times, and many communities filled theirs with waste.

Myths and Facts about Castle Moats.

Now, let’s answer some myths or facts about castle moats.!

Crocodiles and Alligators in moats (Myth or fact?)?

If you are a castle-moats lover, then you must have come across the common notion that alligators, crocodiles, and all such scary animals were placed inside moats to dissuade attackers from trying to swim through. 

Please discard that notion – It is more of a myth than fact. 

Moats were man-made; they were usually too small and scientifically not suitable habitats for alligators or crocodiles.

Do castle Moats Stink (myth or fact?)

They did but, not anymore. If we reverse back to the middle ages when the castles were in use, the architects built the latrines (toilets) so that all the excrements would be dropped into the moat.

So we can imagine what smell persisted near the moat, not the best place to go for a walk.

Today, the castles have a modern plumbing system, so you probably won’t find a stinking moat.

Fishes in moats (Myth or fact?): 

Another often-quoted statement is that moats contained fishes.

Again, this appears to be an assumption that has historical relevance. History tells us that it is highly probable that some communities/ castle owners reared fishes and other small seafood in moats. 

Such that in the event of a famine or scarcity, the moats were backup food reserves. 

In some moats, you are allowed fishing today at the same time admiring the ruins, like the KIRBY MUXLOE CASTLE in England.

Can you swim in a moat of a castle (myth or fact?)

It solely depends on you. Security protocols may or may not allow it, however. Also, if the moat stinks, nobody would want to.

Other Uses of moats

In contemporary times, the uses of moats have changed radically. Castles no longer have moats as a necessity. 

The reasons for this differ. First, assaults no longer come by way of underground digging or siege towers. 

Nowadays, assaults are in the form of bullets using more advanced mechanisms. Additionally, moats have also attained decorative purposes.

Although castle moats are now more decorative than functional for residential purposes, moats now also have architectural and warfare usages. Thus, for example, we now have anti-terrorist moats built for specific purposes.

Why Do Castles Have Turrets?

Castle turrets are conspicuous beauty features for castles such that they are almost impossible to miss! But whose idea was it to attach a tiny tower to the top of a building? Is it just aesthetics, or is there an exciting history behind turrets?

In the medieval era, castle turrets served as security towers from where soldiers defended a castle. But as time advanced, their purpose changed. History shows that towards the 17th century, they became wholly decorative.

Castle Turrets

What are castle turrets?

The word ‘turret’ is a derivative of the Italian word ‘torretta’ which means little tower. Its Latin equivalent is ‘turris’, which translates to mean tower in English.

 So, technically, castle turrets are little towers. However, they are not just any kind of tower; they are little towers attached to a castle at the top. They usually tilt outwards from the building and also have a clear open roof (as in turrets in medieval times) or a decorative pointy top (as in most recent turrets). 

The History of Castle Turrets

Why castle turrets? 

Castle turrets have initially been attached to castles as a military defence system. Master masons built the earliest turrets with access from the main castles through which soldiers could enter and repel any attack.

In the medieval period, military threats came by way of swords, knives, arrows, slings, and the likes; there were no guns at the time.

 Due to how castle turrets were designed and built, it was easy to defend a castle from there with the very minimal casualty. So, castle turrets were famous at the time for their safety benefits.

The defensive design of castle turrets – beauty plus purpose

The medieval engineers always built turrets with class and purpose in mind:

  • Castle turrets were made of tall walls/ towers all around it so that no attack could easily reach those hiding behind the walls. The stones used for constructing turrets were usually similar to the ones on the main building.
  • Castle turrets had slit windows through which the soldiers could shoot, but other areas were primarily covered, making it difficult for arrows to penetrate.
  • Castle turrets were designed to slant away from the castle in a way that from there, a person could see 360 degrees (roundabout) the castle to which it was attached.
  • They had stairs or access doors into the castles through which soldiers can enter, but usually no access point from the outside.
  • Castle turrets were attached to the top of the building; to evenly distribute their weight and not cause harm to the castles, its builders support them with corbels (a solid piece of material in the wall attached to the edges of the building and giving support). 

What were castle turrets used for?

The architects used Castle turrets for military fortifications; they were excellent weapons of war and one of the most robust defences front-line for castles. Some of the uses of turrets are as follows:

  • Castle turrets were perfect for surveillance of the environment, such that persons approaching the castle could be spotted from miles away.
  • It was safe to launch attacks/defence for the soldier (due to lower contact and higher casualty for those outside).
  • From castle turrets, soldiers can easily see the adjacent walls and environment and could shoot at them.
  • Towards the 18th century, castle turrets started to lose their military value (because new assault weapons like guns had begun to surface). From then on, it started gaining its current decorative purpose, especially in Scottish Baronial Style. 

In 1800, castle turrets resurfaced again alongside the vast popularity of Victorian architecture.

Castle turrets vs towers

Castle turrets are different from towers in the following way: Castle turrets are attached to the top of the castle and supported by corbels, whilst castle towers are entire structures built from the ground. 

Also, a castle tower may or may not be attached to the castle itself, but a castle turret is always an offshoot of the main building.

Medieval castles had turrets, and many courts still do today.

Modern castle turrets are, however, very different from ancient ones. They are now desired solely for decorative purposes. The slit windows have now been replaced with broad windows, and they are no longer loaded with ‘ready for war’ equipment.

The most famous Castles with turret

Lastly, what’s a meal without a little bit of dessert. Having served you the main course of the origin and uses of castle turrets, let us add a list of the most famous castles with turrets. 

If you are a castle turret lover, then these places are a must-visit!

Why Do Castles Have Drawbridges?

Usually, the drawbridges are what you step on before entering any castle, but why do so many forts have them?

A castle drawbridge
In article about: Why Do Castles Have Drawbridges?

The Castles had to have a drawbridge when they were surrounded by a dip trench or a moat giving daily access to the fortress and worked as a crucial defence feature during a castle siege. It stopped the unwanted getting inside the courtyard and also protected the castle’s main gate.

Are you falling in love with castles? 

Below you will find everything you might want to know about medieval drawbridges.

The drawbridges origins 

There is evidence that Egyptians were the first who used mechanisms like drawbridges for the first time 4000 years ago.

But widespread use of drawbridges didn’t happen until the early Middle Ages, the times of the castle boom when the architects faced the challenge to enhance them with as many defence features as possible.

When they added moats to the early fortresses as the first line of defence, the habitants needed practical access inside.

This was when castle builders came up with a solution of a movable bridge, a wooden deck just long enough to reach the other bank of the moat.

It was vital for the residents to get in and out daily, but the most crucial role it played when the fort was under attack.

It made it impossible for any soldiers or war machines to reach the gates or portcullis and break them.

The early drawbridges were relatively simple, and few men could easily remove them when needed.

Later towards the 13th century, along with weapon evolution, the drawbridges became more advanced and used mechanisms like pulleys and winches to raise and lower them.

On your trips to the Castles, you might have noticed that they are restored and just working as standard bridges; only a few castles have operational drawbridges.

Types of drawbridges 

I was surprised to find out how many different movable bridges the engineers designed throughout the Middle Ages.

Here is a list of types of drawbridges and not only; 

  • Overhead crane
  • Chain and arrow drawbridge
  • Chain drawbridge without boom
  • Drawbridge without boom tilting up
  • Rigid transmission drawbridge
  • Flexible transmission drawbridge
  • Movable bridge without counterweight
  • Simple movable weighbridge
  • Modern overhead crane

Overhead crane drawbridge 

Not a pretty traditional drawbridge as we used to see, but it did have the same end goal.

This bridge would be slid out at the bottom of the gate with the help of a windlass (a horizontal barrel) until it reaches the other end of the trench.

Technicians connected the bridge with the rope or chains to the windlass and, when rotating, would start sliding the actual deck. 

You will find examples of such mechanisms at Fort de Lèvis (Canada) and Fort de Loncin (Belgium).

Chain and arrow drawbridge

One of the simplest examples where the boom had a counterweight and a chain at the back.

The back of the boom inside will be pulled down as the other end lifts the bridge with the help of the chains attached to it.

Such a drawbridge you can notice at the castles like Castle of Lassay and Chateau Pierrefonds.

Chain drawbridge without boom

This type of drawbridge is a variation of the chain and arrow drawbridge. The counterweights are suspended behind the deck beams, making it easier to raise the deck when operating the winch.

Exemples: Porte de Sens à Villeneuve-sur-Yonne (France), Château de Bonaguil (France).

Drawbridge without boom tilting up

It is one of the most uncomplicated and best systems of drawbridges used in the Middle Ages.

It consisted of a perfect balanced deck that you could lift by pulling the back end inside the building without extra arrows or booms above.

The men in charge will lower it with the help of a winch or windlass connected to the deck with chains or rope.

Moreover, it was an extremely efficient system during a siege as it didn’t have the chains and arrows exposed to artillery’s fire.

Therefore, these types of movable bridges were successfully used up until the early 18th century.

Examples; Castle of Dinan (France); Stronghold of Mornay.

Rigid transmission drawbridge

The first example of this system dates from 1697, and it was utterly perfected in 1762 by the engineer of King Alexander-Magnus of Oppenheim. 

It eliminates the frame counterweight and replaces it with metal bars weighted with cast iron sleeves. 

The coordination of movements is done only by chains passing over pulleys. A modification of the metal arms was made in 1831 by the engineer captain Romy.

Examples: 

  • Porte Saint Léon in Bayonne – Richerand-d’Obenheim system
  • Fort l’Écluse in the town of Léaz – Bélidor system
  • Fortress of Bonifacio – Belidor system modified by Delile
  • Fort Victor-Emmanuel on the Barrière de l’Esseillon in the town of Aussois – Porte contrepoids.

Flexible transmission drawbridge

Jean-Victor Poncelet designed such a system in 1820 where the counterweight of the chains acting on the apron is formed by a string of heavy links which descends into a pit as the apron rises, a manoeuvre which could be possible in a relatively small space.

A fine example of an “à la Poncelet” system can be seen at Porte Saint-Paul in Verdun (France).

Many other engineers contributed to improving this system in the following years, known as Gueze and Mangin system, Lacoste System, Deffeux System, Derché System, Devèze System.

Examples

  • The forts around Paris – Poncelet system.
  • Saint Paul de Verdun gate – Variable counterweight Poncelet system.
  • Lunette du Petit-Sainte-Foix in Sainte-Foy-lès-Lyon – Lacoste system variable counterweight
  • Porte de Secours de la Bastille in Grenoble: variable counterweights Gueze and Mangin system
  • Citadelle du Rabot in Grenoble: variable counterweights Gueze and Mangin system
  • The door of the keep of the Bastille in Grenoble: variable counterweight Deffeux system
  • Porte de Bienne in Bayonne  : Constant counterweight Derché system.
  • Fort de Troyon  : Constant counterweight Devèze system.

Movable bridge without counterweight

English lieutenant Adagt invented a simple mechanism in 1877 and installed it at the stronghold of Toul, France.

To raise the bridge, you needed to unlock the rear of the deck, which was equipped with casters descending to the bottom of the ditch by its weight, guided by two curved rails, thus raising the front permanently held to the masonry of the work.

Such a system can also be found;

Simple movable weighbridge

Again like the type mentioned above is quite an unsophisticated model, where the apron is raised using a chain rolling on rollers.

Examples:

Redoubt of Salettes in Briançon (France), 

Napoleon model towers

Modern overhead crane

The overhead crane is the successor of the medieval sliding floor. The engineer L. Mauvais proposed in 1867 a movable bridge both in weighing down and rolling. 

The main drawback of these latter movable bridges was that they required constructing unique premises for manoeuvring and surveillance.

Examples:

  • Metz Arsenal (France)
  • The entry of peace to certain forts of the second belt of Lyon (France)
  • The start of the war at certain forts in Verdun (France)

Do all castles have drawbridges?

Around 60-70% of castles existing today don’t have drawbridges; either it wasn’t a part of the initial design, or the castle didn’t have a moat or a deep trench that made it necessary to have a drawbridge.

What are the disadvantages of a castle’s drawbridge?

The disadvantage of a medieval drawbridge was in its composition. The artillery could seriously damage the wooden deck during a siege, making it difficult for the owners to restore it afterwards.

Final Thoughts 

It’s hard for us today to fully understand how vital the movable bridges were back then, but one thing we can be sure of is that they made the forts a much safer home.

If you can’t wait to admire an operating drawbridge, you might want to visit the Tower of London, Langeais Castle, Château du Taureau.

And we believe there are more that are not much advertised on the internet that is worth visiting.
