"Atop Nymph’s Hill, a quick climb from the Plaka, is the National Observatory of Athens, a research institute and true observatory. Visitors by day get a lovely view of the city from the tree-lined grounds which surroundbeautiful mid-19th-century neoclassical buildings designedby Theophil Hansen; and visitors by nightget a chance to view celestial bodies through a 170-year-old telescope. In 2017,theobservatory was the site of an extensiveinstallation by Argentinean artist Adrián Villar Rojas."

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

I was on the tour here. It was very simple. Long time was spent explaining eclipse mechanics. All what my child studied in the 2nd class. No models or special tools were used while they have them. An ancient mechanic calendar was shown but also not in action. The only positive part was the final observation of Saturn

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
