St Patrick's Isle

St Patrick's Isle is a tidal island off the coast of Peel that holds the remains of a medieval fortress. The site spreads across roughly two hectares and is enclosed by a substantial defensive wall containing various fortifications and building structures.

Scandinavian rulers built an initial wooden fortress here in the 11th century, which was later replaced by a massive stone structure. The red sandstone walls visible today were constructed during a major expansion in the 14th century.

This place was a religious center for centuries, as shown by the remains of a cathedral and monastery still visible in the ruins today. Visitors can see how spiritual life was intertwined with defense on this island.

Access to the island is controlled by the tides - at high tide it is separated from the mainland, while at low tide it can be reached on foot. Visitors should check tide times before visiting and wear sturdy shoes, as paths can be uneven and sometimes wet.

The underground crypt beneath the cathedral ruins is accessible to visitors and offers an unusual glimpse into the depth of the site. Archaeological digs in the 1980s uncovered burials from the 10th century here, including a notable female grave.
