 Later it became associated with the Bruce family, who, during the 14th century, built a strategic tower-house called Clackmannan Tower and in the 16th Century built a mansion alongside the tower.The mansion was demolished when local branch of the Bruces died out in 1791, although its stones may have been recycled to build the new parish church in 1815.It still stands above the town according to Historic Scotland, but entry is forbidden (because of subsidence).
