Peel Castle

Peel Castle is a castle in Peel in the Isle of Man, originally constructed by Norwegians. The castle stands on St Patrick's Isle, which is connected to the town by a causeway. It is now owned by Manx National Heritage and is open to visitors during the summer.

The castle was built in the 11th century by Norwegians, under the rule of King Magnus Barefoot. While there were older stone Celtic monastic buildings on the island, the first Norwegian fortifications were built of wood. The prominent round tower was originally part of the Celtic monastery, but had battlements added at a later date. In the early 14th century, the majority of the walls and towers were built primarily from local red sandstone, which is found abundantly in the area. After the rule of Norway, the castle continued to be used by the Church due to the cathedral built there – the see of the diocese of Sodor and Man – but was eventually abandoned in the 18th century.
