The ruins which stand near the water are those of a Franciscan friary, founded in the mid-15C. The cloisters date from the end of that period. Although part of the original plan, the six-storey tower was not added until later on. The south side of the church has been considerably expanded. The buildings to the east include the sacristy and the chapter-house; the kitchen and the refectory to the north are built over a stream.
