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!

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 🇬🇷✨

Really interesting tour with a knowledgeable guide. It's a short but lovely walk uphill with good views over the city and the Acropolis. I learned a lot about the history of the observatory and the use of astronomy, and enjoyed seeing Saturn and its rings through the telescope.

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

This is a must-do on the list of things to hit while in Athens. It was so cool to hear about the history of the observatory and then getting to actually look through the telescope was awesome. The view of the Acropolis from up here is insane as well. For 5 euros and an hour of your time, you have to do this. Greek tour is at 9pm, with an English one at 10pm. They're on Wednesdays, Fridays and Saturdays.
