Hunterston Castle, West Kilbride, North Ayrshire is the historic home of the lairds of Clan Hunter. The keep dates from the late 15th, or early 16th centuries, while the attached manor house is of the 17th century. The estate was granted to the Hunters by David I of Scotland in the 12th century, and the heads of the clan have lived on the estate for the following 900 years.
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.
