The National Observatory of Athens (NOA; Greek: Εθνικό Αστεροσκοπείο Αθηνών) is a research institute in Athens, Greece. Founded in 1842, it is the oldest research foundation in Greece, as it was the first scientific research institute built after Greece became independent in 1829, and one of the oldest research institutes in Southern Europe.
Around 1840, the national benefactor, Baron Georgios Sinas, ambassador in Vienna, expressed his intention to make a donation for science development in Greece. He took advice from his friend, the Austrian ambassador in Athens Prokesch-Osten, who knew the Greek-Austrian physicist and astronomer Georg Constantin Bouris. Bouris became the first director of Athens Observatory, and was also involved in the construction of its first building.

Excellent guided tour of the oldest observatory in Athens. Extremely interesting copy of the Antikithyra mechanism, the oldest analog computer found on earth. Be prepared for strenuous sitting or standing arrangements.

Just a breath away from busy Acropolis and Thiseion, immerse yourself in a time travel to the 18th century Athens! Beautiful walks, amazing buildings, gardens and the oldest observatory of the Greek capital. 5*****
