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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
