The Abbey of St Mary (also known as St Dogmaels Abbey) is Grade I listed ruined abbey in St Dogmaels in Pembrokeshire, Wales, on the banks of the River Teifi and close to Cardigan and Poppit Sands.[1]
It is the ruins of a medieval abbey, originally founded in 1115 by the Fitzmartin family of Cemais. It was established by the Order of Tiron, a medieval monastic order, which owned a large number of priories and abbeys in France, England, Wales, Scotland and Ireland.
It is now in ruins, but substantial parts of the abbey remain, including the western end wall, the north wall, the north transept, and eastern walls of the crypt. There are also several monastic buildings which survive to the south of the abbey and a detached 13th century building, most likely an infirmary, which is located to the south east.[2]
