Sackville Street is a thoroughfare located in the Mayfair district of the City of Westminster, London. It connects Piccadilly to the south with Vigo Street to the north.
The street was developed in the late 17th and early 18th centuries on land that was part of the estate of the Sackville family, specifically the Earls and Dukes of Dorset. It is historically significant for its architectural preservation; the west side of the street is noted for containing one of the longest continuous terraces of original Georgian houses remaining in central London, dating primarily from the 1730s.
Historically, Sackville Street has been associated with professional services and high-end commerce. During the 19th and early 20th centuries, it was known for its concentration of medical practitioners and tailors, the latter due to its proximity to Savile Row. Notable residents and establishments have included the antiquarian booksellers Henry Sotheran Ltd, which has occupied premises on the street since 1936.
The street remains primarily commercial and professional in character, housing various offices, galleries, and specialized retail businesses. It falls within the Mayfair Conservation Area, a designation intended to preserve the historical and architectural character of the neighborhood.
