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.
After his Indian campaign[1] in 1399, Timur (Tamerlane) decided to undertake the construction of a gigantic mosque in his new capital, Samarkand.
[8][9] During the centuries the ruins were plundered by the inhabitants of Samarkand in search of building material, especially the brick of the masonry galleries along with the marble columns.
During these restorations, a band of inscriptions revealing Surat al-Baqarah of the Quran was added to the main sanctuary iwan of the mosque.
Nevertheless, the dome cannot be seen from the courtyard, for whole building is covered up from inside by the grandiose pischtak, which framed a monumental, deeply embedded iwan.
Their cover was formed from the juxtaposition of many small, flat brick vaults and domes supported by a forest of more than 400 marble columns and buttresses.
Four other, more majestic minarets that flanked the Portal arch of the entrance and the Pischtak of the main domed building are not completed yet.
In the middle of the courtyard is located the stone pedestal—the huge Quran stand[18]—crafted from ornate marble blocks.
The huge Bibi-Khanym Mosque with its three domed rooms, the covered galleries and the open courtyard was intended to gather the entire male population of Samarkand city for the joint Friday prayers.
This dome construction allowed the main hall of the mosque to be committed to the proportions and the aesthetics of the 30 m high interior above the mihrab.
