Belgravia is a district of central 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, although the estate has been forced to sell many of its freeholds to their tenants at much below market value due to the Leasehold Reform Act 1967.
