Mayfair is the most expensive property on the standard British "Monopoly" board at £400, and is part of the dark blue set with Park Lane. It commands the highest rents of all properties; landing on Mayfair with a hotel costs £2,000. The price is a reference to the property values in the area, which have remained consistently high, with real-life rent as much as £36,000 per week. At the time the board was being designed in the 1930s, Mayfair still had a significant upper-class residential population.
