I have a rather morbid request: a Nazi concentration camp. I'm tinkering with a World War 2 mod, need a unique building for the Nazi German civilization, and can't think of anything more symbolic of their evil than to replace jails with death camps. I found one for Civilization 3 here, but don't know how to port it over to Civ 4.
Here's a POW camp. Close enough for your purpose?
