Ulugbek Observatory

Ulugbek Observatory in Samarkand is a historical monument and one of the outstanding observatories of the Middle Ages. It was built by order of Mirzo Ulugbek in 1423. Due to the large employment in government affairs and rather rare visits to the observatory, Ulugbek was thinking about closing it. But he was persuaded by the famous mathematician and astronomer Ali Kushchi to abandon such an undertaking. Unfortunately, in 1449 Ulugbek was killed and the observatory functioned for about twenty years. Already in the 16th century it turned into a pile of ruins. For a long time, the exact location of the observatory remained unknown. Back in 1908, after more than 400 years, V.L. Vyatkin managed to find it.
