The Portland stone memorial cross stands in a small war memorial garden to the east of the Cathedral Church of Christ and the Blessed Virgin Mary of Rochester (Grade I-listed), overlooking the High Street. It consists of a tall, blind, wheel-head cross with an octagonal shaft and moulded foot, standing on a base. The base comprises an octagonal drum with a shallow circular head. The base stands on three octagonal steps.
A sword is carved in low relief on the front face of the cross. At the centre of the wheel-head to the rear is a carving of a warship in full sail. The inscription to the front face of the base reads LEST WE/ FORGET/ 1914 1918 with, on the top step, 1939 1945.
