Good work so far; it is indeed in one of the countries mentioned.
It is obviously an old medieval city, and the tower in question is most way up to the top of the hill.
It has been listed by UNESCO as a World Heritage Site.
There is a church at the very top, and bizarrely enough, a school.
Access to the school is via a very long wooden covered staircase.
This picture is looking down, from about 2/3 of the way up:

Any lack of verticality is probably the photographer's fault, not the builders!
