Struell Wells (Irish: Toibreacha an tSruthail; Ulster-Scots: Struell Waals)[1] are a set of four holy wells in the townland of Struell, 1.5 miles (2.4 km) east of Downpatrick, County Down, Northern Ireland (grid ref: J513442).[2] The wells date from before the time of Saint Patrick, and even today are used for people seeking cures. On Mid-Summer Eve (Saint John's Eve) and the Friday before Lammas, hundreds of pilgrims used to visit Struell.[3] The earliest written reference to the wells is in 1306, but none of the surviving buildings is earlier than about 1600. Pilgrimages to the site are well documented from the 16th century to the 19th century.[2] The site is managed by the Northern Ireland Environment Agency.[4]
