Chatham is the major commercial centre in the Medway Towns, merging into the historic City of Rochester to the West, and the town of Gillingham (known mainly for being the home of Will Adams , the first Western Samurai) to the East.  Its significance came from its strong Naval connections, which live on in the Historic Dockyard, the main reason to visit the town. Overlooking the river are The Great Lines which were the first trenches designed for war defences. The town is also known as being the home of Chatham Girls, the rightly ridiculed female residents.
