The famous Market Hall building in Chipping Campden where corn sales were held for hundreds of years.
On the day this picture was taken there were a lot of people in the Market Hall who seem to be tourists, but it is possible a particular event was taking place on the day. The image was captured on Kodachrome film in June 1975 and it's good Kodachrome was used because they have the date marked on them; without that indicator it would be difficult to date this image precisely (although the work 'Marina' on the car in the left hand corner would place it in the 1970s I suppose).
