Smailholm Tower was originally built in the 15th century or early 16th century by the Pringle family. It was designed, in common with all Scottish peel towers, to provide its occupants with protection from sporadic English raids. The tower was attacked by English soldiers in 1543, 1544 and again in 1546, when the garrison of Wark Castle sacked the tower and carried off prisoners and cattle. The castle was successfully defended against the English in 1640, by Sir Andrew Ker of Greenhead.
Smailholm was obtained by the Scotts of Harden around this time. The Scotts – ancestors of Sir Walter – rebuilt parts of the tower and barmkin. In the 18th century the tower decayed, following the family's move into nearby Sandyknowe. The last owner, the Earl of Ellesmere, handed the property into state care in 1950. It was restored in the 1980s, and now operates as a museum.
Smailholm was a relatively small tower house, offering around 200 m2 of floorspace, later extended by construction of a hall house and second kitchen within the barmkin, or courtyard. The rectangular tower is of four storeys, situated on top of a rocky outcrop.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
