Belgravia is a district of west London in the City of Westminster and the Royal Borough of Kensington and Chelsea. Noted for its immensely expensive residential properties, it is one of the wealthiest districts in the world. Much of it, known as the Grosvenor Estate, is still owned by a family property company, the Grosvenor Group, owned by the Duke of Westminster, and the area takes its name from one of the Duke's subsidiary titles, Viscount Belgrave. Owing to the Leasehold Reform Act 1967. the estate has been forced to sell many of its freeholds to their tenants at much below market value.
The district lies mostly to the south-west of Buckingham Palace, and is approximately bounded by Knightsbridge to the north (the street of that name, not the district), Grosvenor Place and Buckingham Palace Road to the east, Pimlico Road to the south, and Sloane Street to the west.
