Ardoch Roman Fort

Ardoch Roman Fort is an archaeological site just outside the village of Braco in Perthshire, Scotland, about seven miles (eleven kilometres) south of Crieff. At Ardoch are the remains of a Roman fort and several marching camps which included a signal tower. Part of the Roman Gask Ridge, it is said to be one of the most complete Roman camps in Britain, and is one of the best-preserved series of Roman military earthworks in the whole Empire. It is protected as a scheduled monument.
