Hammelburg

Those of us who are Hogan's Heroes fans are very familiar with this city (although, to be honest, until I looked it up, I assumed it was fictional). It is an actual city in south-central Germany with a population of 11,000. Stalag 13 on the TV show was supposed to have been near the city.

In real life, during World War II, Stalag XIII-B and XIII-C were in Hammelburg.
