Clough Castle is an excellent example of an Anglo-Norman castle with an added stone tower. A small kidney-shaped bailey lies south of a large mound, originally separated from it by a 2.1m deep ditch. On top of the 25 ft high motte is a stone tower, enlarged to become a tower house in the 15th century. It is sited off-centre as much of the rest of the top of the motte was occupied by a large hall, which apparently burned down. Around the motte is a ditch, and on the south-east side a low crescent shaped bailey, which was probably once joined to the motte by a wooden bridge.
Excavations on the summit of the mound in 1950 revealed that originally (in the late 12th or early 13th century) the top of the motte was surrounded by a timber palisade within which were pits for archers. Also found was the foundation of a long rectangular hall in the north-east half of the area, probably built in the mid 13th century. Later in the same century a small rectangular stone keep was built to the south-west, two storeys high and surviving to this day, having been conserved in 1981-82. In the late Middle Ages, after what appears to have been a period of disuse, it was restored and added to, resulting in an L-shaped tower house.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
