Siraf port, known today as Taheri Port, was a legendary ancient Sassanid port, with foundations dating back to the Parthian dynasty. It was located on the north shore of the Persian Gulf in what is now the Iranian province of Bushehr and was destroyed around 970 AD. Its ruins are approximately 220 kilometers east of Bushehr and 380 kilometers west of Bandar Abbas.Siraf controlled three ports: Taheri Port, Kangan Port and Dayer Port. Siraf was originally was known as Ardeshir Ab due to the fact that Ardeshir Babakan set up a waterway network here in order to facilitate port activities for which he was responsible. Siraf has not been yet registered on the list of national heritage sites of Iran. This is needed so that it will be preserved and maintained.
