National Observatory of Athens - Thissio Visitor Center

The guided tour in this old, beautiful building is amazing. You get to learn a lot about its history and the science of astronomy by a very knowledgeable guide, and then you get to see some stars and planets through a telescope! The whole hill is also very picturesque and has some remnants of ancient greek monuments, as well as a great view of Athens. Perfect for kids as well, and at a really good price!

The Visitor Center in Thissio is located on the Hill of the Nymphs and it is housed in the Sina building. The visitors of the Center will have the opportunity to explore the Geoastrophysics Museum, the library of the Observatory, which contains many historic books and documents, as well as a variety of scientific instruments of the 20th and 19th century. They can also examine from close by the first optical telescopes of Greece, including the meridian refractor of G. Bouris (1846) and the original 16cm telescope housed under the dome of the Sina’s building. The latter was used by Julius Schmidt, the third Director of the NOA (1858-1884), in order to draw the most accurate map of the Moon during that period.

Very nice place. Great view. You can climb up the hill from different ways. Most easy one is to get off train station in thisio and then head up the paved road. The only negative thing is that the place has a lot of garbage here and there.

Visited the observatory at 22:00, after greek visitors. We were in a group of 15 persons. Bought tickets by arriving at the entrance. We observed the moon through a portable telescope, the real one is currently in maintenance. Open only 3 nights per week Good moment

Stunning Views at the Observatoire in Athens! 🌟 The Observatoire in Athens offers breathtaking views of the city and the Acropolis 🏛️! It’s the perfect spot to enjoy a amazing moment while taking in the beauty of Athens from above. If you’re looking for a unique experience with amazing panoramic views, this place is a must-visit 🇬🇷✨

A visit to the National Observatory of Athens in the evening is an experience you won't forget. The tour starts at the Geoastrophysics museum and concludes with a view of the night sky through the Doridis telescope, which is over 100 years old. It's impossible to put into words the entire experience.. A must-see while exploring Athens! Fun fact: You'll also get to see the first topographic map of the Moon from the 19th century!

If you should find the National Observatory of Athens closed, when you arrive, during your visit, as I did in August. Rather than leave, explore a little. You may find that the grounds surrounding the Observatory itself are open to the public, providing the opportunity to view Athens from an unobstructed vantage point. If you're looking for a quiet spot, offering a great view of the city. Without having to wait in line in the city center, this is a great choice.

Amazing experience. The National Observatory of Athens and especially the picturesque Thissio premises are a "live reminder" of the modern scientific history of Greece and a bearer of the future of Greek science. The tour included a visit to the museum which is full of historical instruments, books and telescopes used in the past, as well as to the Doridis telescope, a 16" wide and 5m long impressive refractor hosted in a dome. The tour was implemented by very competent and enthusiastic guides who were able to capture the audience's attention and convey their passion for Astronomy. The visit was an experience worth doing and I will do it again with the first opportunity. Congratulations
