The remains of this 5th- or 6th-century monastic settlement are one of the peninsula's more evocative archaeological sites, with low stone walls among close-cropped turf and drifts of white daisies revealing the outlines of beehive huts, storehouses and an early Christian oratory. At least 10 stone crosses have been found, including the beautiful Reask Stone decorated with Celtic motifs. The site is signposted 'Mainistir Riaisc' just off the R559, 2km east of Ballyferriter.
