Normanby Hall, Lincolnshire
Normanby Hall, once the seat of the Sheffields, was built between 1825 and 1830 to the designs of Sir Robert Smirke. Walter H Brierley added wings in 1906. Smirke�s marble chimney-pieces, carved perhaps by one of the Westmacotts, remain, and Smirke�s colour scheme has been restored in the halls, library and music room.
