A tongue of land at Isford is utilised as a motte and bailey castle, the motte, c 8ft high, being placed close to the river (Montgomerie). The inner bailey is protected by the motte and by a short cross ditch. The outer bailey has its own ditch on the N and a higher outer bank for two-thirds of the way stretching across the alluvium. The whole area comprises some 4 acres. It would appear that at some later date the motte-ditch was extended into the outer bailey ... forming, probably, a fish pond rather than serving any military purpose. The inner bailey contains a depression which may represent the site of a pond, and the outer bailey a 'meandering ditch'. The motte has a small rampart bank on its S and SE sides. There is no evidence of masonry or of foundations of buildings on the site, which is grass-covered (Field Investigators Comments–F1 RLBW 05-FEB-53). (PastScape)
The example at Isfield is unusual in its lowland siting. It illustrates an alternative defensive strategy to the high motte and, because of the absence of later disturbance of the site, it retains high archaeological potential.
This unusual motte and bailey castle occupies a low-lying area at the former confluence of the Rivers Uck and Ouse. It comprises a low mound or motte surrounded by a circular moat, a ditch leading eastward from the moat, another dog-legged ditch leading north-eastwards and a broad east-west ditch and bank defining the northern edge. The site was made defensible by the diversion of the River Ouse and the creation of an island 200m by 112m on which the castle was located. This diversion involved the digging of a channel 13m wide between two natural meanders of the rivers on the NE and NW sides. Within the island, another channel was cut taking water from the Ouse around the circular motte and out to rejoin the main stream of the river
In so doing, the island was raised above the level of the floodplain and was divided into a western inner bailey and an eastern, much larger, outer bailey. The central feature of the castle was the motte, which measures 22m in diameter and is raised 1.4m above the level of the surrounding land, or 3m above the base of the surrounding moat. The motte is stepped on the eastern and southern sides owing to a landslip in relatively recent times. On the southern edge of the castle is the site of a rectangular fishpond, 23m by 10m in size and with a drainage leat on the SW side. The dog-legged ditch is interpreted as a later addition to the monument since it is both deeper and more steeply embanked than the other channels. Its purpose is unclear, but it may be connected with the artificial lake created to the north, to which the 1.6m high bank alongside the east-west channel belongs. (Scheduling Report)
During dredging works at Isfield Mill Stream in 1991, part of the ditch of the earthworks adjacent to Isfielf Church were dumped upon a Scheduled Ancient Monument by the NRA. The latter funded sample excavations of the dumped spoil, which yielded pottery of C12-C13 date. (Gardiner 1992)
