Dover Castle was built on the White Cliffs in 12th century; a 75 metre deep well; a view across the Channel.
The Anglo-Saxon church beside it was once probably part of a Saxon fortified settlement: very soon after his victory at Hastings in 1066, this was converted by William the Conqueror into a Norman earthwork and timber-stockaded castle.
Kent, one of the defensive fortifications along the coast of the Channel built as a part of the Device Forts by Henry VIII
Brough Castle is built on the site of a Roman Fort (Verterae, the outlines of which are still just visible), to the south of the town of Brough, and approached through the village of Church Brough, the Castle is undergoing some consolidation work under the care of English Heritage.
Built around 1090 by King William II the Castle has a chequered and bloody history. In 1136 it was seized by the Scots as was Appleby Castle nearby. Both were held by the Scots until 1157 when they were retaken by the English and given by the Crown to Hugh de Morville, though repossessed in 1173. The Scots almost destroyed the Castle in 1174 but between 1179 and 1190 Theobold de Valoines carried out much needed restoration work to improve its withered defences.Thereafter, the Castle stayed in Crown control until 1203 when King John gave it to Robert de Vipont.
