Tehran railway station

Tehran Railway Station (, Istgah-e Rah Ahan-e Tehran) is located in Rah Ahan Square, at the foot of Valiasr Street in the southern part of Tehran, the capital of Iran. The railway station was originally designed in 1928-29 by Polish architect Władysław Horodecki, who died before the construction could begin. In 1930, the experienced Danish railway architect Knud Tanggaard Seest was then tasked to finish the project. Around the time it opened in 1930, the previous tram system in Tehran was shut down. Seest changed the original plans dramatically and gave the railway station a new, highly modern, strict design. Thanks to Seest the Teheran Railway Station is one of the finest examples of early modernistic architecture in the Middle East.
