Harwich is a town in Essex, England, located on the coast with the North Sea to the east. It is in the Tendring district.
Nearby places include Felixstowe to the northeast, Ipswich to the northwest and Colchester to the southwest.
The town received its charter in 1238, although there is evidence of earlier settlement - for example, a record of a chapel in 1177, and some indications of a possible Roman presence.
Its position on the estuaries of the Stour and Orwell rivers and its usefulness to mariners as the only safe anchorage between the Thames and Humber led to a long period of maritime significance, both civil and military.
The town became a naval base in 1657 and was heavily fortified, with Harwich Redoubt, Beacon Hill Battery, and Bath Side Battery.
The Royal Navy is no longer present in Harwich but adjacent Parkeston continues to offer a regular ferry service to Hoek van Holland in the Netherlands.
Many operations of the large container port at Felixstowe and of Trinity House, the lighthouse authority, are managed from Harwich, and plans for the development of a new container port in Bathside Bay were approved by the British government in December 2005.
