Peel Castle, Medieval castle on St Patrick's Isle, Isle of Man

Peel Castle stands on St Patrick's Isle, linked to Peel by a causeway. Its walls of local red sandstone enclose a round tower, a square battlemented tower, and the roofless ruins of St German's Cathedral. The outer wall runs along the cliff edge, with a gabled fragment and smaller ruined turrets visible above the masonry.

The first fortifications on St Patrick's Isle were wooden structures built in the 11th century under King Magnus Barefoot of Norway, on an island that already held Celtic monastic stone buildings. In the early 14th century most walls and towers were rebuilt in local red sandstone. The castle stayed fortified with new positions added as late as 1860, and was abandoned in the 18th century.

The ruins of St German's Cathedral within the fortress show where religious life centered for centuries on the island. Visitors walking through can still sense the layout of the old church and understand its role in the community's spiritual life.

Peel Castle stands on St Patrick's Isle, reached from Peel town by a causeway you cross on foot. Manx National Heritage owns the site and opens it to visitors in summer only, so check opening before travelling outside that season. The grounds are uneven, with ruined walls and the roofless cathedral underfoot.

Archaeological digs between 1982 and 1987 uncovered the grave of a woman buried with Norwegian coins and jewelry from around 1030. The discovery suggests strong trade and family connections between the island and Scandinavia during medieval times.
