Dorset Square is on the site of what was Lord's Old Ground, before the cricket club moved to the present Lord's Cricket Ground in St John's Wood, London. It is to the immediate north of Marylebone Road, and joined on its eastern corners by Gloucester Place and in the west by Balcombe Street.
The east side (1-8) and the north side (9-20), are all Grade II listed. The Embassy of El Salvador, London is at no 8.
