For those interested in entering the “Hall of Time,” unlocking the “Gate to Space,” and conducting a thorough study of the Moon, a visit to the National Observatory of Athens is highly recommended. Founded in 1842, the National Observatory of Athens is the oldest research foundation in Greece. It has long been used by Greek and foreign Astronomers as the basis for astronomical, meteorological, cartographical and geodynamical measurements and observations in the more than 170 years long course of its history. Today the buildings of NOA at Thissio include an Astrogeophysics Museum, housing clocks, telescopes and other instruments of the 19th century, as well as an extensive 19th century library.
