Austria
Franzensburg is a medieval-style castle in Laxenburg, Lower Austria.
Built between 1801 and 1836, it was named in memory of the last Holy Roman Emperor, Francis II, who died in 1835. Franzenburg is part of the Castle Park outside of Vienna.
The castle was never meant to be a residence, but now contains period rooms from the time. It’s setting on an island makes it quite the photogenic spot.
