The Great Lines defensive fortifications are now a Heritage Park and a potential World Heritage site.
The area of the Great Lines fortifications was the site of the medieval town of Chatham. The need for some kind of linear bastioned artillery fortifications was realised after the Dutch Raid of 1667 when the Dutch navy was able to sail unimpeded up the River Medway into the heart of our naval anchorage. This resulted in heavy fortifications being installed along and at the mouth of the river.
