a municipal borough and market-town of England, in the west riding of Yorkshire, situated on the right bank of the Don, here crossed by two bridges, 36 miles S. by W. of York. It was the Damm of Antoninus, and was called by the Saxons Dona Castrum, whence its pre- sent name is derived. The town stands on the Watling Street of the Romans; coins, urns, and other Roman remains are occasionally dug up in the neighbourhood. It received its first charter of incorporation from Richard I. Under the new act it is divided into three wards, and governed by a mayor, six aldermen, and eighteen council- ors. Doncaster is one of the cleanest and most agreeable towns in the kingdom. Among the public buildings the principal are the mansion house, a handsome structure, used for meetings of the corporation, concerts, &c., and which cost about £10,000; Christ Church, erected in 1827–8, for which a sum of £13,000 was bequeathed by the late J. Jarratt, Esq., a native of this place; the town-hall, gaol, theatre, market-house, &c. The parish church of St George was a spacious and elegant structure surmounted by a fine tower 141 feet high; but it was recently burned down and is at present (1854) in course of being rebuilt. There are a grammar and other schools, a public library, savings-bank, dispensary, union workhouse, Yorkshire institution for the deaf and dumb, and numerous public charities. About a mile S.E. of the town is the race-ground where the cele- brated Doncaster races are held annually in the third week of September. They continue for five days. The grand stand is a magnificent and commodious edifice. Doncaster has several iron and brass foundries, and manufactories of sacking and linen. Market-day Saturday. The corn mar- ket is one of the largest in the kingdom. Pop. (1851) 12,052.
