The Ulugh Beg Observatory is an observatory in modern day Samarkand, Uzbekistan, which was built in the 1420s by the Timurid astronomer Ulugh Beg. This school of astronomy was constructed under the Timurid Empire, and was the last of its kind from the Islamic Medieval period[1]. Islamic astronomers who worked at the observatory include Jamshid al-Kashi, Ali Qushji, and Ulugh Beg himself. The observatory was destroyed in 1449 and rediscovered in 1908.
