The Azadi Tower is often seen in tourist brochures, but they never tell you that the thing is located in the middle of the largest roundabout in Iran. Getting to it can be a bit nerve-wrecking, depending on what direction you approach it from. There is an underpass somewhere, and I recommend using it.

The thing was built to commemorate the 2,500th anniversary of Persia, which is the most remarkable thing about it. It's just 50 meters tall, a lot less than I had imagined.
