Description

Rochester City Walls are historic city walls primarily from the 13th and 14th centuries, incorporating Roman remains, with later repairs and partial rebuilding. There are four surviving sections:

The first section, off The Common, runs north to south for about 30 meters and is in a fragmentary state with little facing stone remaining, with some parts supporting later structures.

The second section, off Free School Lane, is the most impressive and well-preserved, featuring a northeast circular bastion that is two stories high and has three lancets in the upper stage. The upper courses of the attached wall are mostly rebuilt, but a short stretch still has coped merlons.

The third section, which encloses the City Ditch, was rebuilt when the city walls were extended further out in the mid-14th century and retains a much-reduced southeast bastion.

The fourth section, off St Margaret's Street, is short and has undergone significant renewal. The walls are designated as a Scheduled Ancient Monument.
