Linden House bastle, Humshaugh. Photo by Peter Ryder.

Linden House was created in the 19th century probably by combining two or three separate properties. One of the walls in the house is 1.3m thick and may have been part of a 16th or 17th century bastle house. The history of the building is difficult to make out as there seem to be at least six different phases of building. The original house may have been converted into a bastle in the early 17th century, but there is not yet enough evidence to prove this. This is a Grade II Listed Building protected by law.
