Of the mediæval castle there remains only a considerable part of the wall of the _enceinte_, and, it may be, some ancient masonry built up into Sir William Harrington’s house, which is still inhabited. This is said to have been the gatehouse; if so, it was that of the northern ward, and was upon the line of the wall dividing the one ward from the other. The curtain wall is about 7 feet thick, and 25 feet to 30 feet high, and composed of flint rubble. The battlement is gone or nearly so, and there remains but a part of one mural tower, circular in plan, which capped the south-east angle of the wall of the northern ward. The wall covers the northern and most of the eastern sides of the area. There is no trace of it along the western or river side. No doubt it was less substantial on that side, upon which the natural defence was strong. The south or smaller ward does not appear to have been walled in. It was covered on the three sides by the river and the marsh, and may have been palisaded only. The wall evidently crossed the ditch of the mound, and abutted upon it, or possibly upon the shell keep, all vestiges of which are gone. The present entrance to the castle is at the eastern angle of the ditch, which is traversed by a road leading to a small and apparently modern doorway in the wall. There is no trace of a main entrance in this direction, but it must be confessed that if the main entrance lay to the south of the gatehouse, it must have been difficult to approach, save by water. HOPTON CASTLE, SHROPSHIRE. About five miles south-east of Clun, upon a tributary of the Teme, is placed the parish and castle of Hopton, the Opetune of Domesday, when it was, like Clun, held by Picot as the successor of Edric. It was a fief of Clun. In 1165 it was held by Walter de Opton as two knights’ fees under Geoffrey de Vere, one of the three husbands of Isabel de Say; and Peter de Opton held it in 1201. William de Hopton may have followed, but Mr. Eyton is not clear whether he may not have been of Monk-Hopton in the same county. However this may be, Walter de Hopton held the fief in 1223, as did another Walter, 1255–72, and was bound to provide for the defence of Clun Castle one soldier all the year round, and a second for forty days in time of war. In 1304–5, upon the death of Walter de Hopton, he was seized of the Vill of Hopton with its hamlets, and a considerable property about it, chiefly held under Clun, as continued to be the original two fees, by Sir John de Hopton, in the 21 Richard II. The family seems to have remained at Hopton till the reign of Elizabeth, but the castle was still standing and of sufficient strength to be held for King Charles in the seventeenth century. It was taken after a gallant resistance, and dismantled. [Illustration: HOPTON CASTLE.—_Ground Plan._]
