Takkyubin Observatory Of Constantinople
Built by Taqi ad-Din Muhammad ibn Ma'ruf in 1577, the Constantinople observatory of Takkyubin (Taqi ad-Din) was one of the largest astronomical observatories in medieval world. However, its glory wasn't meant to last and it was destroyed in 1580, just three years after it had been built, because it wasn't just used for astronomy, but for astrology as well, a form of divination which is outlawed by the Sharia.

You left out the Pharos of Alexandria. At an est. 103-118m tall, it was so huge that they have no idea what they could have used for fuel to keep the flame burning that big and bright.
