Historical Overview

Foundations and Early Development

The Kandilli Observatory traces its roots to 1868, when it was founded as the Imperial Meteorological Observatory. Its transformation into a comprehensive research institute began in the early 20th century, spearheaded by Fatin Gökmen, who envisioned a center advancing both astronomy and seismology (Kandilli Observatory History). The observatory’s location on İcadiye Hill was chosen for its elevation, providing optimal conditions for astronomical observation.

Expansion and Modernization

By the 1930s, Kandilli had established international collaborations and acquired advanced scientific equipment, becoming a regional leader in solar physics and seismic research. The observatory published its first formal report in 1934 and conducted pioneering field studies following significant earthquakes, setting the standard for on-site seismic research in Turkey (Kandilli Observatory History).

In 1982, the institution was reorganized as KOERI, becoming part of Boğaziçi University. This transition expanded its research scope, incorporating departments focused on geodesy, earthquake engineering, and geophysics (Kandilli Observatory History).

Role in Earthquake Research and Public Safety

KOERI operates one of the world’s most sophisticated seismic networks, providing real-time earthquake data and playing a vital role in public safety, particularly during events such as the 1999 İzmit and 2023 Kahramanmaraş earthquakes (Kandilli Observatory Earthquake Monitoring). Its leadership in earthquake monitoring has made it a cornerstone for both scientific advancement and disaster preparedness.

Cultural and Scientific Significance

With a manuscript collection of over 1,300 works in Turkish, Arabic, and Persian, the observatory is recognized by UNESCO’s Memory of the World Programme (UNESCO Memory of the World Nomination). The observatory’s contributions to Islamic calendar calculations, earthquake research, and astronomical observation have made it a symbol of Turkey’s dedication to science (Muslim Heritage).
