Barcaldine Castle is an early 17th century stone L-plan tower house, founded by Sir Duncan Campbell of Glenorchy. Of three storeys and an garret, the wing is slightly offset beyond the west gable of the main block. In the re-entrant angle is a circular stair tower and its ground floor entrance, is still defended by an iron yett. With a first floor hall and a vaulted basement which contains the kitchen and cellars, crowning three angles are large bartizans. There were minor alterations in the early 18th century but by the mid 19th century the roofless castle had been abandoned. In the early 20th century, the many shot-holes and gun-loops were block by harling, when the Black Castle was restored back into a laird's dwelling house. 7 miles south-west is Dunstaffnage Castle and 10 miles north is Castle Stalker.
