Barr Castle, Galston

This five storey red sandstone tower castle still stands as a prominent feature within the boundary of Galston, East Ayrshire. It was also known as Lockhart's Tower and was built as a fortress to control the nearby access points up the Irvine Valley in the 15th century. It is the town's oldest building, with its walls restored through Lottery Funding and the building now maintained and used by the local freemasons as a Lodge for meetings. The renowned revolutionary preachers John Knox and George Wishart (who was martyred) spouted forth here in 1545 and 1556 under the protection of the owners - the Locharts who were staunch Reformers (opponents of Catholicism). 
More frivolous pursuits around the castle included games of handball against the rear windowless wall by local tradespeople. The interior can be viewed on Open Doors days by the public. It's great to see this still standing in this small Irvine Valley town.  One day Galston may become part of the Ayrshire Heritage Trail with sufficient backing from the tourism industry, government and businesses. 
Many locals want to see more effort to regenerate the traditional buildings in the centre.  It has real potential as the oldest of the Irvine valley towns with a history of weaving muslin and silks, and weavers' involvement in the 19th century Chartist movement with its drive to gain political rights and influence for working class people.
