The scaffolding came down first—and with it, four centuries of Islamic astronomical progress.

The Astronomer Who Defied a Sultan: Taqi al-Din's Observatory Burns

When the Greatest Islamic Observatory Was Demolished by Royal Decree

The Ottoman Empire destroyed its greatest astronomical observatory in 1580 after clerics convinced the Sultan it attracted evil spirits.

The scaffolding came down first. On the morning of August 22, 1580, Ottoman soldiers climbed the hill overlooking the Golden Horn, their orders clear: dismantle everything. The Istanbul Observatory—the most advanced astronomical facility in the Islamic world—would be rubble by nightfall.

Inside, Taqi al-Din Muhammad ibn Ma'ruf watched through a window as workmen approached with ropes and hammers. At sixty-four years old, the Syrian polymath had spent five years building what he called his "house of the stars." His mechanical clocks could measure time to the second. His sextants rivaled anything in Copenhagen or Uraniborg. He had promised Sultan Murad III that the heavens themselves would reveal Ottoman destiny.

That promise had destroyed him.

When a great comet blazed across Constantinople's sky in 1577, Taqi al-Din declared it an omen of victory—and indeed, Ottoman armies soon crushed Safavid Persia. But then came plague. Then drought. Then death, spreading through the capital's narrow streets like divine wrath. The chief religious judge, Kadizade Ahmed Shemsettin, whispered in the Sultan's ear: the observatory was an abomination. Man had no right to spy on God's secrets.

💡 Taqi al-Din invented a rudimentary steam turbine and described escapement clock mechanisms nearly a century before European clockmakers developed similar technology.
