Ballinbreich Castle is a ruined tower house castle in Fife. The castle was built in the 14th century by Clan Leslie, and subsequently rebuilt several times. There may have been an outer curtain-wall though this no longer survives. Much of the present structure is of 16th-century date. It is a three-storey L-plan castle and overlooks the Firth of Tay.
Early maps of the castle by Timothy Pont and John Adair at the National Library of Scotland show the castle within a curving wall or earth bank. From the air, two curving enclosures can be seen, the crop mark remains of ditches. The inner area was probably the 16th-century garden, and rectilinear crop marks within the larger enclosure may have been later garden features.
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.
