Three squares on the Monopoly board do not technically exist.You could walk still further if you traipsed up and down the Mayfair grid system. It's possible to walk 2.6km from St James's Palace to Ludgate Circus without leaving the Monopoly board.Had we included them, we'd have chosen Battersea Power Station (electricity) and the former New River company (water) at Sadler's Wells. We've also left off the utilities for similar reasons.The Tower of London might fit the bill, and is still closer to existing properties on the board. Then again, it's actually a mile or so distant. Speaking of which, we've left off the Jail - it's not clear which of London's many lock-ups is intended, although it's tempting to plump for Pentonville, given that it shares its name with one of the light blue properties.The orange squares, for example - Vine Street, Marlborough Street and Bow Street - were all locations associated with the law. Other properties were clustered thematically. Some of the streets are grouped together by locality - Pentonville Road, Euston Road and (only pub on the board) The Angel Islington all grace the same part of town.
