This is the heart of Belgravia, once the preferred address for the gentry's London town houses, though now mostly occupied by organizations, embassies, and the international rich. The Square and the streets leading off it share a remarkably consistent elegant architectural style thanks to all being part of a Regency redevelopment scheme commissioned by the Duke of Westminster and designed by Thomas Cubitt with George Basevi. The grand, cream-colored stucco terraced houses were snapped up by aristocrats and politicians due to their proximity to Buckingham Palace just around the corner, and still command record prices on the rare occasion when they come onto the market. The private garden in the center is open to the public once a year (www.opensquares.org). Walk down Belgrave Place toward Eaton Place and you pass two of Belgravia's most beautiful mews: Eaton Mews North and Eccleston Mews, both fronted by grand rusticated entrances right out of a 19th-century engraving. Traffic can really whip around Belgrave Square, so be careful.
