The curative well is of great antiquity, named after St Cawrdaf, the C6 saintly brother of St Cadfarch, who was also associated with curative wells. The well house today is a structure of the mid-later C19 erected to cover and protect the basin. The waters were known and used until the C19 for the healing of all manner of ills.


The well house is a small rectangular building built into the hillside with views over Criccieth Bay. It is approximately 2m x 1m wide internally, built of brindle brick with a slate roof and angled clayware ridges. It is open to the SE facing a stream to which the overflowing waters run.


The interior consists entirely of the rectangular basin. The walls have been limewashed.
