The North side of the Registan square was reconstructed during the 17th century. At the place of the Ulugbek caravansarav “Mirzoii” by order of Jalangtush Bahodur the construction was erected to combine a madrassah and a mosque. The construction of the madrassah and mosque took almost fifteen years from 1646 to 1660. Tilla-Kori is not like other madrassah in the plan. The portal of the mosque and gallery with domes lying on powerful octahedral foundations are turned into a court yard.
In the interior painting kundalcolor technology with gold leaf painting on the relief ornament — is widely used. Near the mihrab (a niche specifying a direction to Mecca) the minbar is located (a place for the imam-preacher). The mosque court yard served for Friday prayers.
