If you could spend a year in any real world location during any period of history, which would you choose and why?

Geek Question of the Day: I know a lot of us are students of history, so tonight I thought it might be fun to ask you; If you could spend a year in any real world location during any period of history, which would you choose and why? Assume that as long as you didn't do anything crazy, you'd survive the trip. Oh, and you can't take any non-period-appropriate things back with you! =)
