Kensington Palace Gardens

Kensington Palace Gardens is a street in west central London with some of the most expensive properties in the world. It was the location of the London Cage, the British government MI19 centre used during the Second World War and the Cold War.A tree-lined avenue half a mile long in the heart of embassy land, Kensington Palace Gardens is often cited as the "most exclusive address" in London, according to real estate agency Knight Frank. It is one of the most expensive residential streets in the world, and has long been known as "Billionaires Row", due to the extreme wealth of its private residents, although in fact the majority of its current occupants are either national embassies or ambassadorial residences. As of mid-2012, current market prices for a property in the street average over £22 million.It is immediately to the west of Kensington Gardens and connects Notting Hill Gate with Kensington High Street. The southern section of Kensington Palace Gardens is called Palace Green.
