Here are the details of maps for Warlingham:
"A sad place, its village green a roundabout and a public garden, its cottages replaced piecemeal by shopping arcades" wrote Ian Nairn of Warlingham, but this map shows it when it did still have a village green. The village lies in the SE area of the map, which stretches north to Hamsey Green, west to Warlingham Court Farm. Our author Richard Oliver, an acknowledged expert on the Ordnance Survey but also here a local lad, suggests cycling round the map: "not so many streets have been constructed since 1910 that there is much danger of getting lost" he says. An 1899 directory of Warlingham is included.
