According to annals from that period Racoo monastery was founded as a church by Patrick and Brìd in 440 A.D. The site contains the tomb of Assicus, Patrick's copper/silversmith.  Assicus was one of several metalsmiths who worked for Patrick and produced such items as St. Patrick’s Bell (now located in the National Museum of Ireland).  Assicus was the first Abbott-Bishop of Elphin in Roscommon, but lived as a hermit for some years on Rathlin O’Beirne Island.  He died on a return journey to Elphin and is buried at Racoo.
