@spearthrower, Well ok, I'm a non-native English speaker, so I wasn't aware of the connotations for Bazaar. On the other hand, I'd still say that the market place is often the central place too, but I'm not able (and not at all keen on) proofing that with empirical data, you're apparently not either, so let's just keep it at that.
On second thought, a central square as a city improvement isn't that bad, it does make sense and it could also be tied to stability.

But I am still against your wells and inns

The cemetery on the other hand is ok for a city improvement, but I'm not aware of any graphics. And can you tell me what the difference is between a barracks and a "military training ground", SadoMacho? The Stable has only been introduced because cavalry units needed a boast (and Mongolia a UB), so giving Infantry too a +Exp bonus would negate the Effect.
I want to restate the Pagan Temple thing, call it Cult place, Sacred place/area or so, it'd be a bit livlier than a cemetery.
