Cadogan Square (/kəˈdʌɡən/) is a residential square in Knightsbridge, London, that was named after Earl Cadogan. Whilst it is mainly a residential area, some of the properties are used for diplomatic and educational purposes (notably Sussex House School).
The square is known for being one of the most expensive residential streets in the United Kingdom, with an average house price of around £5.75 million in 2013.[1] Milner Street runs from the middle of the west side of the square.
