Location of Kandilli Observatory

Kandilli Observatory, or more formally Kandilli Observatory and Earthquake Research Institute (KOERI, Turkish: Kandilli Rasathanesi ve Deprem Araştırma Enstitüsü) is a Turkish observatory, which is also specialized on earthquake research. It is situated in Kandilli neighborhood of Üsküdar district on the Anatolian side of Istanbul, atop a hill overlooking Bosporus.[2]


The observatory, named originally "Imperial Observatory" (Ottoman Turkish: Rasathane-i Amire‎) as established in 1868 in the Rumelian side of Istanbul, was dedicated mainly to weather forecasting and accurate timekeeping.

During the 31 March Incident in 1909, the observatory was destroyed by the rebels. Next year, however, Professor Fatin (later Fatin Gökmen) was tasked with the reestablishment of the observatory. He chose the present place as the location in Anatolian side of Istanbul. Systematic research works began on July 1, 1911. After several name changes, the name "Kandilli Observatory, Astronomy and Geophysics" came into use in 1940. In 1982, the observatory was annexed to Boğaziçi University. Later, the institution was renamed Kandilli Observatory and Earthquake Research Institute (KOERI).[3]
