Observatory was built by the order of Ulugbek and is undoubtedly one of the achievements of that time. Ulugbek himself together with his mentor Kazy-zade Rumi were the authors of this structure.
Until now, nothing has survived from the observatory building, except for a part of the underground measuring instrument. It is a deep trench, carved in marble, with degrees and minutes engraved along the edges. It was part of a huge sextant that rose from the ground to the very roof of the observatory.
Nothing else has survived, but in the museum, built right there, you can see graphic reconstructions and models of the building. Looking at the roof, you understand that it was built so that it would be convenient to observe the objects in the sky. The observatory made it possible for astronomers to observe stars and create a catalog of these stars.
