THE TOWN WALLS
extended in a line with the Castle Gates across the isthmus down to the banks of the river, having a corresponding barrier on the other side of the castle. It was erected by Robert de Belesme, third Norman Earl of Shrewsbury, under the idea that his father’s fortifications were not of sufficient strength to withstand a siege from the forces of Henry I. which in 1102 marched against him (page [14]).
An additional rampart called Roushill, enclosing the space between the wall of Earl Robert and the Welsh bridge, was added during the Commonwealth. These walls for many years served as a communication between the northern and western parts of the town; but in 1835 the more modern portion was nearly buried in the formation of a new road.
