Historical monuments of Samarkand

The Ulugbek Madrassah was built by the Ulugbek’s order and guidance. It lasted only three years from 1417 to 1420. When the medresse was constructed, Ulugbek gave lectures on mathematics and astronomy till his death.
Two years later, the ruler of Samarkand Yalangtush Bahadur ordered to build the copy of the Madrassah, and the second Sher-Dor Madrassah was built opposite it. The only difference was that it had two more winter teaching halls, but the main structure was the same as in Ulugbek Madrassah.
Several years later, the same ruler of Samarkand ordered the third Tilla-Kari Madrassah. It’s outward is the same as those two other medresses, but coming in you’ll see a one story building. To make the architectural ensemble, the architecture made two floors on the outside but only one inside. Madrassah was always built by one project – four-cornered yard with four terraces and cells along the whole perimeter. The main entrance was always locked with lattice and two other entrances were used by purpose. The doors in cell were always low because “Islam” means “obedience”, that is why everyone who entered or went out of cell always had to bow, it was like greeting and wishing health to everyone.
