Holy shit. That was awesome 326 :O
It would be great if this kind of "structure" would occur naturally, you know like a huge hole in the middle of no where.
Aww yeah, minecraft forum suggestion time.

Delete bump :
Just finished one of the 4 towers on one of the 4 corners of the city :P Tell me what you think.
NOTE : If anyone wants to put any chests there, put them in the part of the tower closest to the interior of the city, because the outside part is griefable (even if that's against the server rules, we don't want any trouble).
