OULOUGH BEGH OBSERVATORY

Unfortunately, there is so little left to see of this famous observatory that some people will "miss out", which would be a mistake, because the only view of the underground part of the giant sextant is worth the visit: an 11 m arc lined with marble parapets where the degrees are indicated. The site of the observatory was long lost in memory and was rediscovered at the beginning of the century by Viatkin, a schoolmaster with a keen interest in archaeology, whose tomb can be seen at the entrance to the site. Ulugh Begh was a scholar, poet and mathematician, considered one of the greatest astronomers of his time. While telescopes were still unknown at the time, he wrote an astronomical catalogue with the coordinates of more than 1,000 stars. He was able to determine the rotation cycle of the planet Saturn as well as the length of the stellar year with less than one minute of error. But his son, allied with religious fanatics, put an end to his work by assassinating him in 1449. Not content to make the man of science disappear, who dared to discuss the existence of God with his students, the fanatics destroyed his achievements and especially the most disrespectful: the observatory which housed the largest sextant in the world: 90 °, while the usual sextants are 60 °. The circular building, 45 m high, had three levels with walls decorated with frescoes depicting the stars and the solar system. The descriptions of the time make us bitterly regret their destruction. The whole site was ransacked, the stones used for other constructions, and the underground part of the sextant completely buried, only to be rediscovered centuries later.

The museography has been reworked. But the museum has gained in lighting and enhancement what it has lost in museographic funds. Fewer astronomy-related objects will be found here than in the old building: in particular, the ceiling with its vaulted ceiling and the astronomy tables of Uulough Begh have been lost, and the focus has shifted to a few objects from the Timurid period that are of no real interest and, above all, devoid of any explanation or connection between them. The large mural depicting the life of Uulough Begh, and in particular his assassination by his own son, has been replaced by two fairly conventional scenes that stick with the official story for which a parricide has no place in a museum.
