Pursuing the Newmarket Road, we find (at the point where it at last ceases to be a Barnwell Street, and crosses the railway into the open country beyond), yet another tiny ancient church, called traditionally the "Lepers' Chapel." It is of Norman date, and probably served the Lepers' Hospital, which we know to have existed hereabouts, as remote as might be from the town. This hospital was endowed by King John with the tolls of the great Fair held hard by on Stourbridge Common, which even so late as the Eighteenth Century boasted itself the largest and most important in all Europe, a position now claimed by that of Nijni Novgorod in Russia. And, to judge by the accounts that have come down to us, the boast was not unfounded. The Cambridgeshire historian, Carter, writing in 1753, thus describes it: "Stourbridge Fair ... is set out annually on St. Bartholomew by the Mayor, Aldermen, and the rest of the Corporation of Cambridge; who all ride thither in a grand procession, with music playing before them, and most of the boys in the town on horseback after them, who, as soon as the ceremony is read over, ride races about the place; when returning to Cambridge each boy has a cake and some ale at the Town Hall. On the 7th of September they ride in the same manner to proclaim it; which being done, the Fair begins, and continues three weeks; though the greatest part is over in a fortnight. "This Fair, which was thought some years ago to be the greatest in Europe, is kept in a cornfield, about half a mile square, having the River Cam running on the north side thereof, and the rivulet called the Stour (from which and the bridge over it the Fair received its name) on the east side, and it is about two miles east of Cambridge market-place; where, during the Fair, coaches, chaises, and chariots attend to carry persons to the Fair. The chief diversions at Stourbridge are drolls, rope-dancing, and sometimes a music-booth; but there is an Act of Parliament which prohibits the acting of plays within fifteen miles of Cambridge. "If the field (on which the Fair is kept) is not cleared of the corn by the 24th of August, the builders may trample it under foot to build their booths; and, on the other hand, if the same be not cleared of the booths and material belonging thereto by Michaelmas Day at noon, the plough-men may enter the same with their horses, ploughs, and carts, and destroy whatever they find on the premises. The filth, dung, straw, etc., left behind by the fair-keepers, make amends for their trampling and hardening of the ground.
