RAYLEIGH, Essex (Fig. 27).--"In this manor Sweyn has made his castle."[596] Sweyn was the son of Robert Fitz-Wymarc, a half English, half Norman favourite of Edward the Confessor. Robert was Sheriff of Essex under Edward and William, and Sweyn appears to have succeeded his father in this office.[597] Sweyn built his castle on land which had not belonged to his father, so Rayleigh cannot be the "Robert's Castle" of the _Anglo-Saxon Chronicle_, to which some of the Norman adventurers fled on the triumph of Earl Godwin.[598] There is a fine motte at Rayleigh, and a semicircular bailey attached; the ditch round the whole is still well marked. There is not a vestige of masonry on the surface, but some excavations made in 1910 revealed stone foundations. The inner bailey covers 3/4 of an acre. The value of the manor had risen since the Conquest, but it was only a small one, with no villages in its soke. RICHARD'S CASTLE, Herefordshire (Fig. 27).--There can be little doubt that this is the castle referred to in Domesday Book under the name of Avreton, as it is not far from Overton, on the northern border of Hereford.[599] Richard's Castle is almost certainly the castle of Richard, son of Scrob, one of the Normans to whom Edward the Confessor had granted large estates, and who probably fortified himself on this site. At the time of the Survey Richard was dead, and the castle was held by his son Osbern, and it is noted that he pays 10s., but the castle is worth 20s. to him. Its value was the same as in King Edward's time, a fact worth noting, as it coincides with the assumption that this was a pre-Conquest castle. There is a high and steep motte at Richard's Castle, and a small half-moon shaped bailey.[600] There are remains of a stone wing wall running down the motte, and on the top there is a straight piece of masonry which must be part of a tower keep. The area of the inner bailey is 2/3 of an acre. Avreton was not the centre of a soke, but appears to have lain in the manor of Ludeford. [Illustration: FIG. 27. Rayleigh, Essex.
