Iran Chogha Zanbil DSC_3877
It's not until you stand next to the ziggurat of Chogha Zanbil that you get a sense of size... The ziggurat itself measures 105 by 105 metres and originally reached 52 meters in height in five levels, of which 3 terraces remain, reaching 25 metres. The construction of this ziggurat may appear as a series of platforms built one upon the other, but the construction is actually a series of concentric towers, each reaching back to the ground independently. Accordingly, whilst only three 'levels' are visible, the remains of all five towers are all still intact - inside the ziggurat.
There's not much tourism in Iran, and those that go, go to Isfahan and Shiraz (Persepolis). So in absence of a tourist in shot, the lower level is about a meter high.
