It is at the lowest bridging point of the River Medway, about 30 miles from London. The town forms a conurbation with neighbouring towns Chatham, Rainham, Strood and Gillingham. Rochester was a city until losing its status as one in 1998 following the forming of Medway and failing to protect its status as a city, the first city to do so in the history of the United Kingdom. There have been ongoing campaigns to reinstate the city status for Rochester. In 2011 it had a population of 62,982.
