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:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
