What Kilmartin Castle looked like in its prime.
A compact three-storey Z-plan tower house of grey rubble masonry set low in a grassy glen. The main rectangular block is flanked by at least two corner towers, one clearly cylindrical with a conical slate roof; steep slate roofs and a prominent gabled end rise above small rectangular and slit windows. Thick stone walls, visible mortar joints and a large stone chimney punctuate the roofline. The castle sits beside a small outbuilding and fenced garden with rolling hills behind.
Its story
The story of Kilmartin Castle.
Kilmartin Castle was built in 1550 for John Carswell, Rector of Kilmartin, and later came into the ownership of Clan Campbell. It is a Z-plan tower house standing in Kilmartin Glen in Argyll, a historically significant landscape that is also home to Kilmartin Museum.
The castle fell into ruin for about two centuries before restoration in the late 20th century. Today the 16th-century tower serves as luxury self-catering accommodation, sleeping ten, and hosts a handful of small weddings each year.
