Neighboring on the Caspian Sea and the Republic of Azarbaijan, this city is of great political and economical significance. The Province of Ardabil has been blessed with splendid natural beauty and numerous sights. It is located on an open plain 1,500 m above sea level, just east of Mount Sabalan (4,811 m), where cold spells occur until late spring.
The province is believed to be as old as the Achamenids (ca. 550–330 BC). It is mentioned in the Avesta, where prophet Zoroaster was born by the river Aras and wrote his book in the Sabalan Mountains. During Parthian era the city had a special importance among the cities of Azarbaijan. Some Muslim historians attribute foundation of Ardabil to king Piruz I of Sassanid Empire. The Persian poet Ferdowsi also credits the foundation of the city to Piroz I. Ardabil suffered some damages caused by occasional raids of Humsbetween 4th to 6th century AD. Piroz repaired those damages and fortified the city. Piroz made Ardabil the residence of provincial governor (Marzban) of Azarbaijan..
