Located along the River Moy, Rosserk Abbey is a compact friary of the Third Order Franciscans, founded around 1440 by a member of the Joyce family. It is just 4km from Killala, County Mayo.

The friary has been in ruins since the Suppression of the Monasteries by King Henry VIII, around 1540, but remains well preserved. Visitors can view the finely carved west doorway, single-aisle church and unique double piscina.
