Bandar-e Anzali is the oldest and biggest port of Caspian Sea. It is significantly important in terms of goods transportations through the sea. Bandar-e Anzali started functioning as a trade port in 1921. The first ship that berthed here was a German one. Two breakwaters of Ghazian and Anzali were later constructed in order to reduce the intensity of sea waves and provide better safety to the incoming and outgoing ships. These two breakwaters are also important from the tourism point of view. Moreover, two bridges were built by German and Swedish engineers to connect the port to Miyan Poshteh and Ghazian.
