Old Scatness is an archeological site consisting of medieval, Viking, Pictish, and Bronze Age remains. It has been a settlement for thousands of years, each new generation adding buildings, and leveling off old ones. A broch was discovered in 1975 and has been dated to 400-200 BC. The site is managed by the Shetland Amenity Trust. In the summer, costumed guides provide tours of the site and the replica Iron Age and Pictish buildings. The visitor centre also includes exhibits, and there are demonstrations of ancient crafts.
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.
