Llandeilo Llwydarth is an ancient area in the foot of the Preseli Hills that borders Llangolman, Maenclochog, Llanycefn and Llandeilo, Wales. It is also the site of an ancient legendary church, linked to Saint Teilo and his skull, which was thought to have healing powers when water from the nearby well was drunk in it.[1]
The church today lies in ruin, and the skull is kept in the south chapel of Llandaff Cathedral in Cardiff.[2]
There remain several wells in the area, with some being high in minerals.
