The castle is situated on a low natural mound, which was originally surrounded and defended by marshy ground.

In the 17th century, the tower was sold to the Pringles of Stichill, who made additions to the building, and enlarged the windows to suit the less dangerous times.

[1] The tower is entered by a door in the re-entrant angle, which retains its original iron gate or yett.

The kitchen has a broad fireplace, slop drain and cupboard in the north wall, with a hatch overhead into the hall.

The walls are of rubble construction, using local basalt with red sandstone for detailing, and finish at crowstep gables.
