Radiating with six straight avenues from a central square (Imam Khomeini), Hamadan is one of the oldest continually inhabited towns, centers of civilization, and numerous capitals of different dynasties that have ruled Iran through the ages. Capital of the province of Hamadan, at the foot of Mount Alvand, and located at an altitude of 1,829 m above sea level, it is 400 km to the southwest of Tehran by road via Qazvin, and can be reached by air as well. It is a trade center for a fertile farm region where fruit and grain are grown.
In the modern Hamadan which is built on the plans prepared by the German architect Karl Fritsch, nothing is left to be seen of ancient Ecbatana or the Medes capital before they formed a union with the Persians. Hamadans climate is mild and delightful in summers, and cold in winters. Early spring and late autumn are the rainy seasons for the region. To this day Hamadan is a very popular retreat with Iranians during the warmer months when the climate in autumn and spring is one of the most pleasant in the country, but winters are long and sever.
