The castle was placed upon the left or northern bank of the Wye, east of and below the city bridge, the cathedral, and in some measure the city, of which it occupied the south-eastern corner. Though excluded from the city liberties, it is, in common with the city, covered at some distance by a steep slope, at the foot of which lies the Yazor brook, which, rising far off to the west beyond Kentchester, and the remains of Magna Castra, supplied the broad tract of lowland still known as Forster’s Moor, Moorfield, Canon’s Moor, Prior’s Moor, Eastern Moor, Moor Barn, and Widemarsh, to the north-west of the city, and which, after skirting its north front below Baron Court, turns Monkmoor and Scult Mills, and finally falls into the Wye, at Eigne Mill, some traces of which remain about half a mile in advance of, and below the castle. The ground thus included is to the north-east, a broad and dry platform of gravel, very fertile, and probably employed as a safe pasture in wild times. The lower tract to the north-west, now drained, and either cultivated or built upon, must, in former days, have been an almost impracticable morass. The city of Hereford, within its walls, was, in plan, about three-fourths of an irregular circle, placed upon the Wye, which forms its concave chord. Its dimensions were, north and south, 600 yards; east and west, 770 yards; and along the river bank, about 600 yards; including the cathedral and the castle. The total girth was about 2,350 yards. The walls—no doubt Norman—upon the older lines, were confined to the landward sides, excepting about 50 yards above the city bridge, and were in length about a mile and a quarter. They were pierced by six gates—Wye Bridge, removed in 1782; Friar’s Gate and Eigne, on the west, removed in 1787; Widemarsh Gate and Bye or Bishop’s Gate, towards the north, removed in 1798; and St. Andrew’s or St. Owen’s Gate, on the east, removed in 1786.
