Unlike the Marvel universe, the DC universe uses "alternate" names for many of their major cities (e.g. Metropolis, Gotham, etc...). As a kid I always wondered what was where, so... I was able to locate a map that lists excatly that (well, for the most part). The map above is one of the more recent maps, but the map below has more detail, though it is a bit dated (from way back to 1990). Nonetheless, its pretty intriguing to find out where things are at - and who is where. I've added a few more links about narratives of some of the major cities - do enjoy!
