Saw aa special on Discovery or Nat Geo and thought this was great. I was a little disappointed after view the show, but still amazed at the work and the craftsmanship that went into building this place. The old saying, they don't build them like this anymore holds true for this place. Probably not a good place for young kids, it is dark and damp and when the tour groups come, it gets crowded quick

This is a quick 15-20 minute visit. It is across the street from the Hagia Sofia. We paid 10 or 15 lira per person to enter. It is dark and wet. Unfortunately, it is very poorly lit. We had been excited to see it since we knew a scene from a Bond flick was shot there, however, you can't really see much of anything. If you use flash, you can get a few shots of columns. There are two columns with Madusa heads for bases. The sign it nowhere near them. Everyone took pictures of blackness looking for them. It was funny because I asked a worker to find out that they were at the very end before turning around and coming back out. If you want to appear really smart and knowledgeable, tell everyone who is bewildered looking for them that they are at then end.

5/5 - Excellent
