Maragheh Observatory

Maragheh observatory (Persian: رصدخانهٔ مراغه‎) also known as Khajeh Nasir Observatory, was an institutionalized astronomical observatory which was established in 1259 CE under the patronage of the Ilkhanid Hulagu and the directorship of Nasir al-Din al-Tusi, a Persian scientist and astronomer. Located in the heights west of Maragheh, East Azerbaijan Province, Iran, it was once considered one of the most prestigious observatories in the world. The observatory served as a model for later observatories including the 15th-century Ulugh Beg Observatory in Samarkand, the 16th-century Taqi al-Din observatory in Istanbul, and the 18th-century Jai Singh observatory in Jaipur.
