In selecting the position advantage was taken of a tongue of high land, broad towards the west and north, but which came rapidly to a narrow and almost abrupt termination in a point about 300 feet above and within the junction of the two adjacent streams. Of these the larger flows along the northern front of the position, and the smaller down a deep valley along its southern front. The two meet a few score yards below the high ground; and upon the left or further bank of the larger stream, and a short distance above the junction, is the church, and attached to it the village, to which the castle and its English lord have given the distinguishing name. It was decided to convert the point or eastern end of the high ground into the proposed strong place, and to form thus, in the northern fashion, an isolated mound. With this intent a broad and deep ditch was cut across the ridge, curved so as to embrace about one-half of the future elevation. At its north end the ditch was carried straight down the hill-side towards the brook. At its south end it came to rather a sharp conclusion, running out upon a natural bank and slope. Here, however, it was in some sort resumed at a lower level, and ended in a shallow ditch at the southern or principal entrance to the castle. The part thus isolated by the ditch formed the circular base of a mound of about 120 yards diameter and about 30 feet high. This the addition of the soil from the ditch raised to about 70 feet, and thus gave it, in the military sense, a command over the adjacent part of the original ridge. On its opposite, or eastern side, the mound does not descend at once towards the junction of the waters, but at its foot is a broad semicircular platform, which covers its east, north-east, and south-east fronts, and from the outer or convex edge of which descends a steep slope towards the water, which slope is again succeeded by inclinations of a far more gentle character, not included in the military works. A fair general idea of this stronghold may be given by supposing a circular platform of 200 yards diameter to be bordered on the east and adjacent sides by a steep natural slope falling from its edge, and on the west and adjacent sides by a steep artificial slope falling to its edge. Then on the western margin is placed a conical table mound, 60 feet or 70 feet high, and about 120 yards diameter at the base, which necessarily converts the western slope into the further side or counterscarp of a ditch, and reduces the eastern side to an open crescent-shaped platform. Such is the original plan of the Castle of Ewias, and such its present appearance after the complete removal of the masonry which for about 600 years adorned or encumbered its earthworks.
