Learn More about Belgravia: Belgravia is an area of Central London in the City of Westminster and the Royal Borough of Kensington and Chelsea. Recognized for its hugely costly residential qualities, it is certainly one of the richest districts in the world. A lot of it, referred to as the Grosvenor Estate is still possessed by the family property company Grosvenor Group, possessed by the Duke of Westminster, although the estate has lately been instructed to sell a lot of its freeholds for their tenants at much below market value because of the Leasehold Reform Act 1967. The district lies mostly to the south-west of Buckingham Structure, and is roughly bounded by Knightsbridge to the north (the street of this title, not the district), Grosvenor Place and Buckingham Structure Road to the east, Pimlico Road to the south, and Sloane Street to the west.
