Northumberland House (also known as
Suffolk House when owned by the Earls of Suffolk) was a large
Jacobean townhouse in
London, which was so called because for most of its history it was the London residence of the
Percy family, who were the Earls and later
Dukes of Northumberland, and one of England's richest and most prominent aristocratic dynasties for many centuries. It stood at the far western end of the
Strand from around 1605 until demolished in 1874. In its later years it overlooked
Trafalgar Square.
