Clacton-on-Sea is the largest town in the
Tendring peninsula and district in
Essex,
England, and was founded as an
urban district in 1871. It is a
seaside resort that saw a peak of tourists in the summer months between the 1950s and 1970s. The town's economy continues to rely significantly on entertainment and day-trip facilities and it is strong in the service sector, with a large retired population. The north-west part of the town has two business/industrial parks. In the wider district, agriculture and occupations connected to the
Port of Harwich provide further employment.
