The Registan ( Uzbek . Registon , from Persian ميدان ريگستان, DMG Maidān-i Rīgistān , 'Square of the Sandy Place') in Samarkand (Uzbek: Samarqand) is one of the most magnificent places in Central Asia. It is the heart of the ancient Samarkand. The ensemble of three madrasas is considered a unique example of the art of urban construction and architectural design of the city's main square. The three madrasas are the Ulug'bek Madrasa (1417–1420) on the west side , the Sher-Dor Madrasa (1619–1636) on the east side according to the Kosch principle and the Tilya Kori Madrasa on the north side of the square (1646-1660). East of the Tilya-Kori-Madrasa is the Scheibanid mausoleum from the 15th century.
The Ulug'bek Madrasa faces the square with its mighty portal and a lancet arch. The corners are decorated with tall, proportional minarets. A mosaic panel above the entrance arch is decorated with a geometric ornament. In the square courtyard there is a mosque, classrooms and, on the edge, rooms that used to be the living quarters of the students. Deep niches (corridors) are spread out around the axis. Originally, the Ulug'bek Madrasa looked very different: a two-story building with four domes over the classrooms, which were located in the corners of the madrasa. The Ulug'bek Madrasa was one of the most prestigious universities in the entire Muslim world in the 15th century. The famous scientist, philosopher and poet Abdur Rahman Dschami studied in this madrasa. Ulugbek also gave his lectures here.
During his reign, this madrasa remained a center of science. The ruler of Samarkand, Yalangtush Bakhodur, directed the buildings of the Sher-Dor and Tilya-Kori madrasa in the 17th century. The Sher-Dor-Madrasa ("tiger containing" madrasa) was the work of the architect Abdujabor. The construction of the madrasa is not as finely divided as that of the corresponding buildings from the 15th century ("the golden era"). Nevertheless, the harmoniously arranged large and small rooms, the finely divided pictures of the mosaics, the monumentality, but also the functional symmetry of this madrasa are among the most impressive architectural monuments in Samarkand.
Ten years later, the Tilya-Kori-Madrasa ("gold-plated" madrasa) was built. This madrasa not only served as an academic teaching facility, but also for a long time as one of the most important mosques. The Tilya-Kori-Madrasa has a two-storey main facade, a large, wide courtyard with small living rooms on the edge (usb. Hudzri ), and four corridors that are arranged around the axis. The mosque building is in the western part of the courtyard. The main hall of the mosque is richly gilded. The Registan Ensemble is a successful combination of buildings from different eras that are currently subject to extensive reconstruction work.
