The Legacy of Ancient Astronomy: Ulugbek Observatory Samarkand in Uzbekistan 🇺🇿🔭
Step into one of the most significant scientific monuments of the Middle Ages.
Built in 1420s by Timurid ruler and astronomer Ulugh Beg, this observatory was once the heartbeat of global astronomical research. Scholars consider it to have been one of the finest observatories in the Islamic world.
Even before the invention of the telescope, astronomers here used a massive underground Fakhri sextant (with a radius of 40 meters) to calculate the length of the stellar year and track over 1,000 stars with incredible precision.
The site features the remains of a massive underground sextant, which was used to observe stars and accurately calculate the tropical year and Earth's axial tilt.
The observatory was destroyed in 1449 after Ulugh Beg's execution, but parts of the foundation and the sextant survived and are visible today.
Today, it stands as a testament to the golden age of Islamic science and a must visit destination in Uzbekistan.
