Tetbury is a town and civil parish within the Cotswold district of Gloucestershire, England. It rests on the site of an ancient hillside fort, on which an Anglo-Saxon abbey was founded, probably by Ine of Wessex, in 681. The population of the parish was 5,250 in the 2001 census, raising to 5,472 at the 2011 census. During the Middle Ages, Tetbury became a vital market for Cotswold woollen and also thread. The Tetbury Woolsack Races, founded 1972, is an annual competition where participants have to carry a 60-pound (27 kg) sack of woollen up and down a high hill (Gumstool Hill). The Tetbury Woolsack Races take place on the "late May Bank Holiday", the last Monday in May annually. Noteworthy buildings in the town include the Church House, Market House, built in 1655 and the late-eighteenth century Gothic rebirth parish church of St Mary the Virgin and St Mary Magdalene and much of the remainder of the community centre, dating from the sixteenth and seventeenth centuries. The Market House is a fine example of a Cotswold pillared market house and also is still in operation as a meeting point and market. Other destinations include the Police Bygones Museum. Chavenage House, Highgrove House and Westonbirt Arboretum lie simply outside the community.
