The Timurid era (772 AH–912 AH) was one of the brightest periods of Islamic civilization and a time of great advancement in art and architecture. Timurid architecture has its roots in the architecture of earlier periods, like the Muzaffarid era. The main style of Timurid architecture flourished within a triangular area between three cities: Mashhad, Samarkand, and Herat, with Herat’s buildings closely resembling those of modern Khorasan, and perhaps serving as a link between Transoxiana and central Iran. During this period, architecture reached an unparalleled level of grandeur and decorative richness, which can be seen in structures like the Ghiathieh Khargird School, Doodar School, Goharshad Mosque, and Bibi Khanum Mosque. The mosques and schools, with unique features such as towering iwans, the use of ultramarine blue mainly on domes, and more, stand out among the remaining works from this era. This study uses library research and a descriptive-analytical approach to explore the architecture of mosques and schools during the Timurid period.
