Reached over a stile and across grassy (but sometimes muddy) fields, the atmospheric and delightful ruins of Athassel Priory sit in the shallow and verdant River Suir Valley, 7km southwest of Cashel. The original buildings date from 1205, and Athassel was once one of the richest and most important monasteries in Ireland. What survives is substantial: the gatehouse and portcullis gateway, the cloister (ruined but recognisable) and large stretches of walled enclosure, as well as some medieval tomb effigies.
To get here, take the N74 to the village of Golden, then head 2km south along the narrow L4304 road signed Athassel Abbey. Roadside parking is limited and quite tight. The welter of back lanes is good for cycling.
