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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
