An island castle, aka insular castle, is a kind of water castle. During middle ages, island castles were built on an artificial or a natural island so that it would be unnecessary to build artificial defences. However, the ones built on lakes were easily captured in winter when the lake was frozen due to their poorly built fortification.
Mont Saint Michel in Normandy, France
The Abbey on the island was built by Richard II, Duke of Normandy in the 11th century as a Romanesque church. Due to the weight of the building, several underground crypts and chapels had to be built, as well. The structure was reinforced and the main façade of the church was built in the 12th century. However, the Mount was besieged and the village was set on fire in 1204. Due to the great damage, Philip II, the King of France, offered Abbot Jordan a grant for the reconstruction of the abbey in Gothic style. Nevertheles, the abbey is seen as a Romanesque structure today.

Trakai Island Castle is a 14th- century stone castle that had great strategic importance in middle ages. The first castle underwent a great damage during an attack by the Teutonic Knights in the late- 14th century. During its restoration in 1409, the wings were added, and it was decorated in a style that was a mixture of Gothic and Romanesque. Additionally, three defensive towers were built in the 15th century, and one of the towers was used as a prison.
After the Battle of Grunwald, the castle lost its strategic importance, and it was turned into a residence. After the wars with Muscovy in the 17th century, the castle was largely damaged and not restored until the 19th century.
