Lochnaw Castle is a 16th-century tower house five miles from the town of Stranraer, in the historical county of Wigtownshire, Scotland.
Lochnaw Castle shows four periods of construction – a simple 16th-century keep, 17th- and 18th-century domestic dwellings, and a mansion-house, which was later demolished. There is a plaque bearing the date 1486, on the SE wall of the keep. A chapel, built in 1704, was demolished c. 1953.
An earlier, ruined castle stands on an island in the nearby Lochnaw Loch. A royal castle, this was given to the Agnews in 1363, but was sacked by Archibald The Grim, 3rd Earl of Douglas in 1390, and subsequently dismantled.
The Agnews remained in the new castle until 1948. The castle, located by the loch, is occupied as a private residence.
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.
