National Observatory of Athens
About

The National Observatory of Athens, founded in 1842, is Greece’s oldest research institution and a landmark of scientific heritage in Southeastern Europe. Perched atop the Hill of the Nymphs in Thissio, the observatory was designed by Theophil Hansen in a distinctive X-shaped layout aligned with the cardinal points. Originally funded by Baron Georgios Sinas, it has played a pivotal role in astronomy, geodynamics, meteorology, and space science. Historic instruments like the Doridis telescope still offer public night sky tours, while modern research continues across its institutes. The Observatory remains a vital hub for scientific exploration and public engagement, bridging past and present through its educational programs and visitor centers.
