The church was built in 1462 as the convent church of the Bridgettine order, and its grey stone walls still carry the solidity of that original construction. Inside, the space is simple and whitewashed, with medieval brick vaulting and a few remnants of the convent's former wealth — carved wooden figures, old epitaphs on the walls.
The church sits at the top of the old town and is open to visitors during the summer season. Services are still held here, and the acoustics are good enough that concerts take place throughout the summer. It is worth climbing the hill even if you only look at the exterior and the view back down over the harbour.
