Ardoch Roman Fort is an archaeological site just outside the village of Braco. 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.
The remains consist of grass-covered earthworks, and are considered among the best preserved Roman earthworks in Britain. The site, which has a complex history, comprises two intersecting forts. The earliest fort is believed to be associated with the campaigns of Agricola (1st century). The later fort was apparently reconstructed within two outer ditches so that this later fort was protected by five ditches on both the east and north sides.
The field to the north is the remnant of a large annexe. Archaeology has demonstrated the existence of a watch-tower (or signal tower) and at least six overlapping marching camps to the north and northeast.
The site was reused in the medieval period when a chapel was built near the centre of the fort. The remains of the graveyard enclosure and the site of the chapel are the only archaeological remains which are visible within the fort.
A hoard of Roman silver coins was found 4 miles north of Ardoch in 1671. At that time, Lord Drummond wrote that the ditches were deep enough to hide a man on horseback. Other trenches to the north east had been damaged by cultivation against his grandfather's orders.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
