The Shir Dar or Sher Dor madrasa was built in the seventeenth century, as a teaching institution and residential school of Islamic sciences. It forms the famed Registan Square ensemble in Samarkand, with the earlier constructed Ulugh Beg madrasa (1417-1421) and later built Tilla Kari madrasa (1646-60). The structure marks a significant continuation of the four iwan, square plan, and Iranian madrasa typology. It reinforces the Timurid emphasis on scale, and resultantly on external facades.
