The biggest, most monumental mosque and Mausoleum af all in Ouzbékistan.
However it is not well preserved. But definately another must see place in the country.
The Bibi-Khanym Mosque (Uzbek: Bibixonim masjidi; Persian: مسجد بی بی خانم; also variously spelled as Khanum, Khanom, Hanum, Hanim) is one of the most important monuments of Samarkand, Uzbekistan. In the 15th century, it was one of the largest and most magnificent mosques in the Islamic world. It is considered a masterpiece of the Timurid Renaissance. By the mid-20th century, only a grandiose ruin of it still survived, but major parts of the mosque were restored during the Soviet period.
