Barnstaple has been the major market for North Devon since Saxon times. Demands for health regulation of its Victorian food market saw the construction in 1855–1856 of a Pannier Market, originally known as the Vegetable Market and designed by local architect R. D. Gould. This has a high glass-and-timber roof on iron columns. At long, it runs the length of Butchers' Row. Market days are Monday – Crafts and General (April to December), Tuesday – General and Produce, Wednesday – Arts Collectables and Books, Thursday – Crafts and General, Friday – General and Produce, and Saturday – General and Produce.
