ROCHESTER TQ 7468 NW TQ 7468 SW 7/2A and 9/2B,C,D Rochester City Walls (formerly listed as The Town Walls) 24.10.50 GV I City walls. Mainly C13 and C14, incorporating Roman remains, with later patching and partial rebuilding. The 4 surviving stretches are distinguished on the map as 7/2A (off The Common), 9/2B (off Free School Lane), 9/2C (enclosing City Ditch) and 9/2D (off St Margaret's Street. None have post office addresses. 7/2A runs N/S for about 30 metres and is in a fragmentary state with little facing stone surviving, some parts underpinning later structures. 9/2B is the most impressive and upstanding section incorporating the NE circular bastion (of 2 storeys with 3 lancets to upper stage). The upper courses of the wall attached are largely rebuilt; a short stretch retains coped merlons. 9/2C, rebuilt when the city walls were pushed further out in the Mid C14 retains the SE bastion, much reduced. 9/2D is short and much renewed. Scheduled Ancient Monument.

A study of the North-East Corner Tower rasies the question as to the Roman walls defensive function. The windows in the second stage of the tower appear to be original but are not defensive in width, even the slit windows would not provide full covering. This implies a decorative function of the tower rather than defensive. (2, 5)
