A few years ago I had a mission in Mianeh, Azarbayjan-e Khavari and saw a ruined bridge named "Pol-e Dokhtar" (="Maiden's Bridge") on my way. Unfortunately, I didn't have a good camera like Olympus those days. Anyway, there are some bridges and even cities in Iran called "Pol-e Dokhtar", but this one is located in Azarbayjan-e Khavari, north-west province in Iran. Some researchers believe that these constructions or cities named "Pol-e Dokhtar" belong to Anahita, the ancient Pre-Zoroastrian goddess of water and fertility. However, another idea says the word "dokhtar" (means "daughter" or "maiden" in Persian) expresses the wish that the construction remains pure and "intact" like a virgin.
