With Bridgenorth, Earl Robert also founded the castle of “Caroclove” in Wales, and such was his need that the works were carried on day and night. He also fortified Arundel, Shrewsbury, and Tickhill. His exertions in 1100 and 1101, when he seems to have built the castle, must have been excessive. King Henry, however, was not less active. He despatched Robert, Bishop of Lincoln, to lay siege to Tickhill, while he himself, having commenced with Arundel, proceeded to Bridgenorth. He took it, after a three weeks’ siege, in September, 1102, and this brought to a close Earl Robert’s short tenure of power in England. The earl fled to Normandy, his earldom of Shrewsbury was forfeited, and Bridgenorth was after a time granted to Hugh de Mortimer of Wigmore, the son of one of Henry’s most trusted supporters. In 1126, Waleran, Earl of Mellent, was here imprisoned, as was Meredith ab Llywarch in 1128. In 1130 wine was sent hither for the king’s use, so that Mortimer was probably rather constable for the Crown than the owner in fee. Mortimer, in the new reign, took the part of Stephen, at whose death he held both Wigmore and Bridgenorth. As he was in rebellion against Henry II., the king took the field against him, and in April, 1155, the castle a second time stood a royal siege. Cleobury, one of Mortimer’s castles, surrendered in July, and Wigmore and Bridgenorth followed. Henry was for some time before the place, and his charter to Stoneley Abbey is dated “apud Brugium in obsidione.” It was at this siege that Hubert de St. Clair is said to have stepped forward to receive the arrow aimed at his sovereign, a romantic but unfounded tale. Henry retained the castle for the Crown, and used it largely as a prison for his Welsh hostages. In 1173-4, when Prince Henry rose against his father, Bridgenorth was victualled at a cost of £22. 5s. 2d. In 1175-6 the king dated a Wenlock Abbey charter from hence. The frequent charges for repairs between 1166 and 1189 show the importance attached to this castle by Henry II. In 1176 the Pipe Roll gives a charge of 1d. per day for the castle porter.
