What is castles surrounded by water?

Castles surrounded by water are known as "water castles" or "moated castles". These castles were often built during the medieval period for defensive purposes and to showcase the power and wealth of the castle owner.

The moats surrounding the castles were typically filled with water from nearby rivers or streams and served as a barrier against attackers. The moats could also be used as a defensive measure against siege engines and to slow down attackers.

Water castles were built in various locations, including on islands, along the banks of rivers or lakes, and on peninsulas jutting out into the water. Some famous water castles include Leeds Castle in England, Bratislava Castle in Slovakia, and Neuschwanstein Castle in Germany.

Water castles were also built for recreational purposes and as status symbols. Some wealthy nobles would build water castles on their estates to showcase their wealth and power and to provide a luxurious setting for entertaining guests.

Today, many water castles have been restored and are open to the public for tours and events. They offer a unique glimpse into medieval life and architecture and continue to be a popular tourist attraction.
