Antalya sure is a hotspot for tentative sites but it remains to be seen if any ever make it. The town itself can only show off the mosque and the surrounding buildings. Why my and the preview review pictures only focus on the minaret is obvious: that's the best part and the other buildings are in ruins.
The mosque is very small and even though I couldn't enter, one can see everything from the doorway. I asked a guy to take a few pics for me but he couldn't go much further in, with a barrier blocking the way. All he could look at that I couldn't see from the door is the opening in the floor showing off the ancient heating method. That doesn't impress me much.
While it's iconic for the town and picturesque from the square nearby, it is no way world heritage material.
