The story of Glenarm Castle begins with a murder. In 1242, John Bisset, a hot-headed young Scot of Norman origin, was implicated in the murder of Padraig, Earl of Atholl, after a tournament in Haddington, where John’s uncle Walter was beaten by the earl. In revenge, John murdered the earl, set fire to his house to conceal the crime, and fled to Ireland.
It was John Bisset who built the first castle at Glenarm on the Antrim coast, facing his old homeland. Bisset then fades from the castle’s history. But every castle worthy of the name needs a good murder in its founding story.
