The Great Lines is over 70 hectares of open space at the heart of Medway. Between Gillingham and Chatham.
The huge expanse of the Great Lines was in its own right a layer of defence to protect Chatham Dockyard from attack.
At its centre is the Chatham Naval War Memorial.

Fort Amherst was constructed as part of a line of gun batteries to protect Chatham’s Royal Dockyard from a land-based attack; the fortifications stretched over 3 kilometres in length and totally enclosed the Dockyard and the village of Brompton. Fort Amherst was, and still is, the most intricate part of the area known as the Great Lines and many areas of the Fort have now been in part carefully restored.
This twenty acre Scheduled Ancient Monument consists of many gun batteries, many with cannon mounted, tunnels and grassy parkland. The parkland is free to visit (now called Great Lines Heritage Park) and is open every day, with easy access and free parking.
