The cemetery of Forthill dates back to the 1500s but the official burial records of this Augustinian cemetery only go back the early 1900s. However, old slabs which have been exposed show burial details dating back to the late 1800s.
Sailors of the Spanish Armada were executed and buried there. A plaque was erected in 1988 by the Spanish Government to mark the 300th anniversary of the Spanish Armada being shipwrecked off Ireland’s west coast.
A corner of Forthill is used by the Augustinian order for the burial of priests and nuns.
