Keswick is an English market town and civil parish, historically in Cumberland, and since 1974 in the Borough of Allerdale in Cumbria. The town, in the Lake District National Park, just north of Derwentwater and 4 miles (6.4 km) from Bassenthwaite, had a population of 4,821 at the time of the 2011 census.
There is considerable evidence of prehistoric occupation of the Keswick area, but the first recorded mention of the town dates from the 13th century, when Edward I of England granted a charter for Keswick's market, which has maintained a continuous 700-year existence. In Tudor times the town was an important mining area, and from the 18th century onwards it has increasingly been known as a holiday centre; tourism has been its principal industry for more than 150 years.
Its features include the Moot Hall; a modern theatre, the Theatre by the Lake; one of Britain's oldest surviving cinemas, the Alhambra; and theKeswick Museum & Art Gallery. The town's largest open space, Fitz Park. Among the town's annual events is the Keswick Convention, an Evangelical gathering attracting visitors from many countries.
