Edward III. resumed possession in 1327, and granted the castle to John of Gaunt, his son, from whom it finally passed into the Duchy of Lancaster, to which it is nominally attached. Henry IV. kept his Easter here in 1429, and Henry VII. continued to appoint a constable and a porter. It is described as “castrum non immensum sed pulcherrimum.” Hertford fared better than most royal castles, possibly from its convenient position as regarded London, for in the reign of Henry VIII. it contained lodgings suitable for the king, and Edward VI. and the Princess Elizabeth were both here. By the latter, when queen, it was alienated to Sir William Harrington, who built a large brick house on the site of the inner gatehouse, which still remains. In the time of James I. the castle is described as covering 7¾ acres. The ditch then extended to the roads or streets now known as the Mill Bridge, the Wash, and Castle Street. The mill was upon the Lea just below the castle mounds. The Church of St. Andrew stands about 150 yards from the remaining mound, beyond the river. There was a second mill, probably that on the river above the castle. The castle was finally leased to Mr. Secretary Cecil, in whose descendant, the Marquis of Salisbury, it remains. It is remarkable that Hertford Castle at no time belonged to the earls who bore the title of Hertford. They were, of course, earls of the county, though this is not specified in the peerages. Their principal eastern seat was at Clare in Suffolk, round which they possessed considerable property.
