Hamedan

Having been the capital of Median, of Achaemenian and then of Parthians and Sassanians, Hamadan has the most illustrating past, the highest elevation and the finest situation of any living city in Iran. Its blue pottery industry, its large green belt, lying at the foot of the Zagros range, and its Alisadr cave which is the longest water cave in the world, add more vitality to this city.
