From a Warminster Town Guide, 1971:
In the 19th century Warminster’s growth continued and the town took on something of its present appearance. New buildings arose rapidly alongside the stately houses of the former wool merchants and in 1830 the Town Hall, in splendid Jacobean style, was opened. The Bath and Salisbury Railway linked the town with its neighbours more rapidly than did the coaches and thus a decline in road traffic set in, a decline that has been reversed in later years of the present century.
