Things to do an see

The building survives today thanks to a preservation order being placed on it in the 1950’s by the Manx Museum Trustees in order to save it from the fate of the surrounding streets which were being demolished to make way for the car park.

Built originally in 1200AD as the first church for the settlement that grew up around Castle Rushen, the building was later developed as a boys’ school.

Inside its Romanesque arches date back to the 13th Century when the building was the Chapel of St. Mary, today its interior depicts the later Victorian school room.
