St Seiroil’s Well in Beaumaris, Wales
Penmon’s history dates to the 6th-century when a monastery was established here by Saint Seiriol. Seiriol created a cell at Penmon Priory and was the son of King Owain Danwyn of Rhos.
Many Celtic churches were associated with these wells. Holy wells were springs thought to have miraculous healing powers and were often visited by pilgrims. Baptisms were also likely to have taken place here.
This well is located in a small building behind a church. Although the building dates to the 18th-century, the flooring and lower parts of the well are believed to be much older.
The foundation and ruins of another building are located next to the well. According to legends, these are the remains of the cell where Seiriol once lived. However, no evidence has been unearthed to support this claim.
