St. Agnes' Church Newmarket

Consecrated in 1887, this small, Victorian church was designed by Richard Herbert Carpenter in the Decorated style and built in the memory of W.S. Stirling Crawfurd, Esquire by his wife, Caroline Agnes, the Duchess of Montrose.

The interior barely seats 100 people,  but the decorations above the altar - including the triple-arcaded Salviati mosaics - may be the most elaborate in all of Suffolk. The chancel on the east end contains a marble reredos, above which are the mosaics that represent the "Angelic Order" and "Heavenly Jerusalem", which were designed by John R. Clayton.
