Built / Designed For: Henrietta Louis, Countess of Pomfret

House & Family History: No. 18 Arlington Street, also known as Pomfret Castle, was the only mid-18th century Gothick style house in London and one of the very few major works by the amateur gentleman architect Sanderson Miller, though there it is unclear whether Miller, Stiff Leadbetter, or Sir Roger Newdigate actually designed the house. Pomfret Castle was built between 1756 and 1759 for Henrietta Louisa, Countess of Pomfret, complete with a Gothick gatehouse on the street, a private forecourt beyond, and the main building, which overlooked St. James's Park. Pomfret Castle's Gothick style made it a complete novelty in mid-18th century London. It was demolished circa 1934 to make way for a block of flats.

Collections: The famous Pomfret Cabinet, made for Henrietta Louis, Countess of Pomfret, circa 1755 (probably by William Hallet), was part of the collection of Pomfret Castle. The cabinet migrated to the family's Northamptonshire seat, Easton Neston, where it remained until 2005, when it was sold for £108,000 during the sale of that house's contents.
