Ulugh Beg observatory

The Ulugh Beg Observatory, built in the 1420s by the Timurid ruler and astronomer-king Ulugh Beg, stands as one of the Islamic world’s greatest scientific achievements. Located on a hill in Samarkand, this pioneering institution housed a massive sextant - a 30-metre curved trench used to calculate celestial positions with unmatched precision. Ulugh Beg and his scholars compiled the Zij-i-Sultani star catalog, mapping over 1000 stars and refining astronomical knowledge for centuries. Though destroyed after his death, the site’s remains were rediscovered in 1908, revealing its groundbreaking legacy. Today, a museum showcases ancient instruments and the observatory’s contributions to science, offering a fascinating glimpse into Central Asia’s golden age of discovery.
