Istanbul University Observatory

Istanbul University Observatory is an astronomical observation facility located on the rooftop of a building at Beyazit Square in the Fatih district. The structure features two rotating domes that house multiple telescopes used for celestial observation and scientific research.

The facility was founded in 1933 when German astronomer Erwin Finlay-Freundlich took charge of the university's astronomy department and established this modern observation center. This project represented a turning point in Turkish astronomy and laid the groundwork for scientific celestial research in the country.

The observatory stands as Turkey's first modern astronomical research facility, marking the nation's advancement in space science education and research.

The observatory sits in a central urban location on a busy square, making it accessible by public transportation. Since nighttime observations are affected by light pollution from the city, the facility focuses on daytime astronomical measurements and specialized research programs.

The facility's primary telescope is a specialized astrograph manufactured by Carl Zeiss that arrived in twelve separate pieces and required meticulous assembly inside the dome. This precision-engineered instrument became a cornerstone tool for astronomical research at the university.
