Βραδινή ξενάγηση - Κ.Ε. Θησείου

Date: 18 July 2018 00:00

City: Athens, Greece

Το Κέντρο Επισκεπτών Θησείου βρίσκεται στον ιστορικό χώρο του ΕΑΑ στο Θησείο στην κορυφή του λόφου Νυμφών, απέναντι από τον ιερό βράχο της Ακρόπολης. Στεγάζεται στο κτίριο Σίνα (βλ. φωτογραφία) το οποίο θεμελιώθηκε το 1842 ύστερα από δωρεά του Γεώργιου Σίνα, επιχειρηματία και γενικού πρόξενου της Ελλάδας στη Βιέννη, και βασίστηκε σε σχέδια του Δανού αρχιτέκτονα Τheophil Hansen.

Σκοπός του Κέντρου είναι η καθημερινή ενημέρωση του κοινού σε θέματα Αστρονομίας καθώς και της σχεδόν δύο αιώνων επιστημονικής και πολιτιστικής ιστορίας του ΕΑΑ, η οποία είναι συνυφασμένη με καθοριστικές στιγμές στην ιστορία της σύγχρονης Ελλάδας. Αξίζει να σημειωθεί ότι στο διπλανό λόφο της Πνύκας ο Μέτωνας πραγματοποίησε τις πρώτες αστρονομικές παρατηρήσεις στην αρχαία Αθήνα με το Ηλιοτρόπιό του.

The Visitor Center in Thissio is located on the Hill of the Nymphs and it is housed in the Sina building (see photo). The construction of the building commenced in 1842 after the generous donation of George Sinas, a businessman and ambassador of Greece in Vienna, and led to the establishment of the Observatory of Athens. The building itself was designed by the Danish architect Theophil Hansen. The site is situated across from the Parthenon and just to the north of the hill of Pnyx, where Meton built his heliotrope in the 5th century BC to perform the first astronomical observations of the classical Greek period.

The goal of the Center is twofold: to inform the general public on a wide number of Astronomy related topics and at the same time to present the nearly two century long history of Greek Astronomy and NOA, a history which has been shaped by the major transitional periods in the evolution of the modern Greek state.
