Barra Castle is an unusual L-plan tower house dating from the early 16th century, about two miles (three kilometres) south of Oldmeldrum, above the Lochter Burn, in the parish of Bourtie,[1] Aberdeenshire, Scotland.[2] It occupies the site of the Battle of Inverurie (1308), in which Robert Bruce defeated John Comyn, Earl of Buchan.[2]
