Dalquharran Castle is a category A listed building in South Ayrshire, Scotland, designed by Robert Adam and completed around 1790. The estate includes two 'castles', the old one abandoned around 1800 and the new one, actually a mansion, which was habitable until the 1960s.
The estate including the old castle were bought in the late 17th century by Sir Thomas Kennedy of Kirkhill, Lord Provost of Edinburgh, and occupied by his son Thomas Kennedy of Dunure.
The castle was arranged symmetrically around a central entrance hall, with top-lit central spiral staircase similar to Culzean Castle, which Adam designed for David Kennedy from around 1776. The house has four floors, with bedchambers in the two floors. The interior was decorated in a classical style. Services were located in the basement. A round bastion turret in the south front contains a drawing room on the ground floor, with library above, with views over Girvan Water. A large oval dining room occupies the east wing on the ground floor.
When the castle was completed in 1790, Thomas Kennedy moved out of the old castle which was abandoned and stands in ruins nearby, about 300 metres southeast, closer to the river.
To the north of the castle, Adam designed a long low stable range connected at either end to the main building by screen walls with gateways, creating a forecourt. The outbuildings were constructed in a simpler style than originally designed by Adam, possible after his death in 1792, with several small lodges arranged symmetrically around the court.
The castle was extended from 1880–1881 by Francis Thomas Romilly Kennedy, grandson of Thomas Kennedy. The property was sold by the Kennedy family in the 1930s to a timber merchant who leased the castle to the Scottish Youth Hostel Association from 1936 to 1939. It was occupied by the evacuated Glasgow Deaf and Dumb Institution during the Second World War. During the war, the estate was sold to John Stewart, a produce merchant, who occupied the new castle with his family and farmed the estate. The castle was eventually abandoned, as it was too large and expensive to maintain. The lead roof was removed in 1967 so the owners could declare it as uninhabitable and avoid paying rates.
Today the interiors are in total ruin; entry into the building was prohibited for safety reasons.
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.
