Hume Castle is the heavily modified remnants of a late 12th- or early 13th-century castle of enceinte held by the powerful Hume or Home family, Wardens of the Eastern March who became successively the Lords Home and the Earls of Home.
Standing as it does, on an impressive height above its eponymous castleton, it commands fine prospects across the Merse, with views to the English border at Carter Bar. It had historically been used as a beacon to warn of invasion. Its enormous walls were created in the 18th century but remnants of the central keep and other features can still be seen.
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.
