FINDING USEFUL GAME MAPS ONLINE : type the type of building or other location you want into your web brouser followed by "maps" or
"floor plans". then do an image search. If you're feeling advenurous try adding "3-d" to the search.
I've tried it with CASTLES, SKYSCRAPERS, OFFICES, LABS, PARKS, ZOOS, SCHOOLS, VILLAGES, CHURCHES, CEMETARIES, FORESTS, APARTMENTS, HOUSES, SHOPING MALLS, SEWERS, CAVES, even AIRPORTS, PRISONS & ARMY BASES.
