Registan became the central square of Samarkand in the 14th century. The word “Registan” can be translated as “a sandy place”. Earlier there flowed a canal forming sand and silt deposits. The sacred Mausoleum of Imam Muhammad ibn Djafar (9th -10th century) was built here in the time of Samanids, which explains the choice of the place. Six streets crossed at Registan. In the time of Temur, Registan was connected with the citadel of Samarkand by a “Silver rows” street. A dome shopping mall, tim Tilpak-Furushon, was built at the crossroad, on behalf of Temur’s wife Tuman-aga. Under Mirzo Ulugbek, Registan became the main official city square where military parades were held and the ruler’s decrees announced. Ulugbek constructed a majestic madrasah and Sufi khanaka with a huge dome. By the 17th century the old buildings of Registan were collapsing and the governor of Samarkand, Yalangtush-biy, built Sher-Dor madrasah instead of Ulugbek’s khanaka and later the Tillya-Kari Madrasah.
