There was a chapel in the Market Place in the 13th century

Lambeth Palace Library, Incorporated Church Building Society (ICBS) archive, file 1476 (www.churchplansonline.org) Reasons for Designation: The Chapel of St Lawrence, Warminster, is designated at Grade II for the following principal reasons: * The small tower, probably late 13th or early 14th century, is a visually important landmark in the town centre. * The Victorian Gothic nave, c. 1855-7, possesses architectural quality. * The site reflects Warminster's medieval expansion from the parish church of St Denys towards the present market place. * Its unusual status as a non-denominational peculiar owned by the borough reflects the fluctuating fortunes of town and church at the Reformation
