HUNTINGDON (Fig. 18).--"There were twenty houses on the site of the castle, which are now gone."[483] Ordericus tells us that the castle of Huntingdon was built by William on his return from his second visit to York in 1068.[484] Huntingdon had been a walled town in Anglo-Saxon times, and was very likely first fortified by the Danes, but was repaired by Edward the Elder. As in the case of so many other towns, the houses outside the walls had to pay geld along with those of the city, and it was some of the former which were displaced by the new Norman castle. Huntingdon was part of the patrimony of Earl Waltheof, and came to the Norman, Simon de Senlis, through his marriage with Waltheof's daughter and heiress. The line of Senlis ended in another heiress, who married David, afterwards the famous king of Scotland; David thus became Earl of Huntingdon. In the insurrection of the younger Henry in 1174, William the Lion, grandson of David, took sides with the young king, and consequently his castle was besieged and taken by the forces of Henry II.,[485] and the king ordered it to be destroyed. The _Pipe Rolls_ show that this order was carried out, as they contain a bill for "hooks for pulling down the stockade of Huntingdon Castle," and "for the work of the new castle at Huntingdon, and for hiring carpenters, and crooks, and axes."[486] We learn from these entries that the original castle of the Conquest had just been replaced by a new one, very likely a new fortification of the old mounds by William, in anticipation of the insurrection. We also learn that the new castle was a wooden one; for a castle which has to be pulled down by carpenters with hooks and axes is certainly not of stone. It does not appear that the castle was ever restored, though "the chapel of the castle" is spoken of as late as the reign of Henry III.[487] The motte of Huntingdon still exists, and has not the slightest sign of masonry. The bailey is roughly square, with the usual rounded corners; the motte was inside this enclosure, but had its own ditch. The whole area was 2-1/2 acres, but another bailey was subsequently added. The value of Huntingdon appears to have been stationary at the time of the Survey, the loss of the twenty houses causing a diminution of revenue which must have been made up from the new feudal dues of the castle.
