According to the NABU (Naturschutzbund Deutschland), up to 8,000 boars live in the German capital Berlin.
(In 2007 there was a huge surge in the wild boar population of 320% and this has probably meant more boar getting bored with country life and moving into the suburbs. I've just been researching a potential trip to Berlin, and I think I'll be taking a spear or two with me.)
