The only construction located and preserved in Bukhara in commemoration of a great astronomer Ulugbek is the madrasah.
The entrance to the madrasah is bifurcated with a crosscutting corridor.
One of ends of the corridor is the darskhona (the lessons room), another one contains the mosque. The facade represents a two-level arcade and has two wings. Two big towers cover it from both sides. The walls and arks are decorated in quite a simple manner. The madrasah is designed with the astral ornament which was undoubtedly a reflection of Ulugbek’s view of the world as an astronomer.
