'Wimbledon' means the hill of a man called Wynnman, or perhaps Winebeald.
The ending 'dun' means a hill: the old village stood at its top, near the common. The name was recorded as Wunemannedunne in 950 and as Wimbedounyng in a charter of King Edgar in 967; a map of 1786 still has Wimbleton. Since 1877 the town has been home to the world's oldest tennis tournament.
