A city located in the midle of Bulgaria
. (Bulgaria is not in the Middle East, and the capitol is NOT Bukarest). Curently Stara Zagora (or StZ for short) is known with the most poisonous air in Europa, some HCL and S and other heavy shit. On entering the city there is a big billboard "Welcome to Stara Zagora - the Center of the Universe"
Other interesting things about the city - it's found 6000 BC, one of the oldest city's in Europa.
