Chipping Campden Market Hall

The hall was intended to provide shelter from the elements for merchants and farmers selling goods like cheese, butter, and poultry (not, as you might think, wool). The side walls were open arches to allow light, and customers, access to the market stalls. The floor of the market hall was made of simple cobbles, now worn smooth by the passage of time and thousands of feet. The building is listed Grade I for its historic importance. In the 1940s the hall was threatened with sale to an American, but local people, alarmed at the prospect of their ancient building being sold abroad, raised the money to purchase the property and gave it to the National Trust. The Hall is still regularly used by local traders.
