The Cumberland Lines were a line of Fortifications consisting of brick lined dry ditches,Bastions,Gun Batterries and other Mitary architecture built in the 18th and 19th centuries to defend Chatham Dockyard from a Landward attack. They are sometimes known by the other names: The Great Lines Of Defence,Chatham lines and Brompton lines.
Most of the lines are on Private land and i DO NOT promote Trespassing on that Land,but recommend you either view the lines from Public accesable land or gain permission from the Land owners.
A great place to see part of the Lines is at Fort Amherst in Chatham.The Fort isn't always open now but check the website http://www.fortamherst.com/ for open days,activities and other bookable events.
