Ulugbek Observatory in Samarkand

Two kilometers northeast of center of Samarkand stands the museum and what had remained of the former observatory. The subterranean part of the sextant is preserved. Ulugbek was the grandson of Tamerlane the Great. He was the scientist, the intellectual and the patron of arts. His scientific and astronomical discoveries greatly advanced knowledge in these fields. Therefore obscurants held grudge against Ulugbek and finally they killed him even though he was the ruler. Then they have destroyed the observatory. When in 1941 all the graves in Gur-Emir mausoleum have been opened the historical information about the assassination of Ulugbek was confirmed.

The biggest observatory was built in 1420s by Ulugbeg. Here, during three decades, scholars, including outstanding astronomers Qazi-Zadeh Rumi, Djemsnid Giyas ad-Din Kashi and Ali Kushchi, had been carrying out measurements of celestial movements. 

The Samarkand observatory became famous for the edition of "Ulugbeg Zidj", containing theoretical introduction and tables of 1018 stars. The observatory was found by Samarkand archeologist Vyatkin V. L at the beginning of the 20th century. He excavated underground remains of huge quadrant of 40 m in radius that was used for observation of the Sun, Moon and other celestial bodies.
