Cairns Castle is a ruined keep, dating from the 15th century. It is located on the northern slope of the Pentland Hills, around 6.5 miles (10.5 km) south west of Balerno, at the south west end of Harperrig Reservoir, in West Lothian, Scotland.[1]
It may have also been known as Easter Cairns Castle, but this may refer to another castle in the area.[1]
