Premise: The Middlewich Folk and Boat Festival takes place in June in Middlewich, Cheshire, England. The festival builds on the town's industrial heritage in which canal boats were used to move coal and other raw materials in the town for the production of salt, and then move the salt out of town, either for use directly, or as a raw material in the manufacture of chemicals such as chlorine and soda ash.
Hypothesis: Middlewich is one of the oldest towns in England.
