Durrow Abbey is a historic site in Durrow, County Offaly in Ireland. It is located off the N52 some 5 miles from Tullamore. Largely undisturbed, the site is an early medieval monastic complex of ecclesiastical and secular monuments, visible and sub-surface.
The extant monuments at the site include a large ecclesiastical enclosure, five Early Christian grave slabs, a fine mid-ninth century high cross, a fragment of a cross shaft, a complete cross-head and cross base, a holy well and other extensive archaeological features. Hugh de Lacy, Lord of Meath built a motte for the Abbey in 1180, and he was killed at the Abbey in 1186 by an Irishman.
