该区位于白金汉宫的西南部，理论上北到骑士桥，东到格罗夫纳坊（Grosvenor Place）和白金汉宫路，南到皮姆利科路，，西到斯隆街（Sloane Street）。

Belgravia (/bɛlˈɡreɪvɪə/) is a district in the west of central London in the City of Westminster and the Royal Borough of Kensington and Chelsea. It is noted for its very expensive residential properties and 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 Duke of Westminster's Grosvenor Group. 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 freeholds to its erstwhile tenants.
