Thanks for these suggestions. Twinning - I can't find any reference to us being twinned with anywhere in the Netherlands, though. Second World War - yes, I thought that too when I first walked past. Nimegen and Arnhem. But then there's Kempis Way as well, which has nothing to do with the war, so I got a bit confused. Dutch Government - I'd read about them being in Dulwich too, but still wonder why they named an estate after them. The mystery continues ....
