Lochmaben Castle was originally a motte-and-bailey castle built south of the current castle in c. 1160 by the Bruce family, Lords of Annandale. King Edward replaced it with a much sturdier structure at the south end of Castle Loch around 1300 and its remains still show the massive strength of its defences. Archibald Douglas, Lord of Galloway, with the assistance of the Earls of March and Douglas, after a siege of nine days, took Lochmaben Castle from the English and 'razed it to the ground' in 1384.
Lochmaben Castle remained important and had a turbulent history until some time after the early 17th century by which time it had seen its last siege and was gradually abandoned. The castle is now protected as a scheduled monument.
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.
