TAMWORTH, Stafford (Fig. 32).--Although Tamworth Castle is not mentioned in Domesday Book, it must have been in existence in the 11th century, as a charter of the Empress Matilda mentions that Robert le Despenser, brother of Urso d'Abetot, had formerly held this castle;[697] now Urso d'Abetot was a contemporary of the Conqueror, and so must his brother have been. Tamworth Castle stands on a motte 50 feet high, and 100 feet in diameter across the top, according to Mr Clark. It is an interesting instance of what is commonly called a shell keep, with a stone tower; one of the instances which suggest that the shell did not belong to a different type of castle to the tower, but was simply a ward wall, which probably at first enclosed a wooden tower. The tower and wall (or chemise) are probably late Norman, but the remarkable wing wall (there is only one, instead of the usual two) which runs down the motte is entirely of herring-bone work, and _may_ be as old as Henry I.'s time.[698] A bailey court, which cannot have been large, lay between the motte and the river Tame, but its outline cannot now be determined, owing to the encroachments of buildings. Tamworth is about a mile from the great Roman road known as Watling Street. We have already referred to the fortification of the _burh_ here by Ethelfleda;[699] probably she only restored walls or banks which had existed before round this ancient capital of Mercia. The value of the manor of Tamworth is not given in Domesday Book. TICKHILL, Yorks (Fig. 32).--The name Tickhill does not occur in Domesday, but it is covered by that of Dadesley, the manor in which this castle was built: a name which appears to have gone out of use when the _hill_ was thrown up. There can be no doubt that it was the castle of Roger de Busli, one of the most richly endowed of William's tenants-in-chief, as it is mentioned as such by Ordericus.[700] He calls it the castle of Blythe, a name which it probably received because Blythe was the most important place near, and Dadesley was so insignificant. Florence of Worcester, when describing the same events, calls the castle Tykehill. The remains furnish an excellent specimen of the earthworks of this class. The motte is 75 feet high, and its area on top about 80 feet in diameter; about a third of it is natural, the rest artificial. Only a slight trace remains of the ditch separating it from the oval bailey, which covers 2 acres. The foundations of a decagonal tower, built in the reign of Henry II., are still to be seen on the top.[701] The bailey retains its banks on the scarp, surmounted now by a stone curtain, which, along with the older part of the gatehouse, is possibly of the time of Henry I.[702] The outer ditch is about 30 feet broad, and is still full of water in parts. On the counterscarp a portion of the bank remains. This bank carried a wooden palisade when the castle was besieged by Cromwell.[703] The site is
