Khajeh Nasir Toosi University of Technology (KNTU), is a public university in Tehran, Iran, named after medieval Persian scholar Khajeh Nasir Toosi. The university was founded in 1928, during the reign of Reza Shah Pahlavi , in Tehran and was named the "Institute of Communications"(Persian: دانشکده مخابرات). It is therefore considered to be the oldest surviving academic institution across the country (Iran has had universities 800 to 2000 years ago from which only the name, ruins and scientific history have survived). This institute was later expanded with an Electronic and Electrical Power Engineering department. The 50th anniversary of the establishment of this academic institute is celebrated in 1978, and a commemorative stamp was also published in this respect by the Post of Iran, prior to the Islamic Revolution of 1979 (See the Photo). The department of Civil Engineering was founded in 1955 as an Institute of Surveying. This institute was later joined by the Institutes of Hydraulic Engineering and Structural Engineering. The department of Mechanical Engineering was founded in 1973.
