The bronze Shrine of Saint Lachtin’s Arm is an important religious relic that was associated with Donoughmore church in Co. Cork.
Dating from circa 1120 AD, it was made to encase a human bone, purportedly belonging to Saint Lachtin. The shrine has a hollow core of yew wood, which originally contained an arm bone. The wooden core is ornamented with elaborate bronze panels that are decorated in zoomorphic interlace, highlighted with silver inlay. The shrine bears a number of inscriptions, one of which is dedicated to its patron. This text reads "A prayer for Maolseachnail O Callaghan, Ard Ri of the Ua Ealach Mumhain who made this shrine" (Maolseachnail died 1121 AD).
