Lochwinnoch is a village on the banks of Castle Semple Loch and the River Calder in Renfrewshire.
Lochwinnoch is mainly a dormitory village for Glasgow and Paisley though it has a long and established history. It was first recorded in the 12th century. Near Lochwinnoch are the ruins of 15th century Barr Castle. In the 18th century there were nine mills operating in Lochwinnoch. Interestingly in the 19th century, local furniture makers were making furniture for the great Clyde-built liners including the Queen Mary and Queen Elizabeth.
The two lochs - Castle Semple Loch and Barr Loch - lie in an area covered by one loch. Watersports are popular and the area is part of the Clyde Muirshiel Regional Park while there is also an RSPB bird sanctuary.
