Corrick Abbey between Newtonstewart and Gortin demonstrates that the Gothic style of architecture introduced to the island with the Normans was known in the Strabane area. Tradition asserts that Enri Aimhreidh O’ Neill (d1392) gave both cattle and land free of tithe for the foundation of this abbey. The remaining structure has a window dating from the fifteenth century with the remains of two quatrefoil windows (four curves forming a cross) within the tracery at the top. These would have originally been set within a pointed arch.
