I enjoyed the two churches, one Orthodox, the other one Catholic, right next to each other.
The citadel is huge, don't forget to visit it underneath where you can find nice alleys where you can walk, bike or roll skating or have a drink at a nice restaurant or hidden pub between the walls. It gives a nice view over...
The Citadel of Alba Iulia is a beautiful and impressive construction.I enjoyed the impressive inner area with cafe's and old buildings.
Inside one of the thick walls there is a beautiful restaurant which has great medieval decoration and good food and ambiance.
