This small island, sitting just 500 metres offshore in a sheltered spot, becomes accessible on foot when the tide retreats. The graveyard complex, designated as National Monument No. 658, encompasses two medieval churches; St Mary’s and St Connell’s; alongside a fragment of a high cross, four cross slabs, and a graveslab. One additional cross slab that once stood here has unfortunately gone missing over the years.

Among these monuments, one particular cross slab stands out for its elegant simplicity. Positioned immediately south of St Mary’s Church, this stone measures 1.8 metres tall and varies in width from 27 to 56 centimetres, with a thickness of about 6 centimetres. The slab bears a Latin cross design with distinctive bar terminals on three of its arms, which divides the stone’s surface into four sections, each containing incomplete concentric circles.

The island setting adds to the site’s atmospheric quality, with its good pasture land providing a peaceful backdrop to these ancient stones. As a complex that brings together multiple periods and styles of early Irish Christian art and architecture, Inishkeel offers visitors a concentrated glimpse into medieval religious life along Ireland’s Atlantic coast. The accessibility of the island at low tide makes it an intriguing destination for those interested in exploring Ireland’s lesser known archaeological treasures.
