National Observatory of Athens

Discover the Wonders of the Sky

The National Observatory of Athens (NOA) is a must-visit destination for science enthusiasts and history lovers alike. Established in 1842, as the first research centre in Greece and Southeastern Europe, it continues to play a vital role in the fields of astronomy, geophysics, seismology, and meteorology. Let’s dive into the fascinating story of this iconic venue perched on the historic Hill of the Nymphs, with stunning views of the Parthenon and ancient Athens and uncover some fun facts about its past and present!

Today’s Observatory Experience
The Visitor Center at Thissio offers an exciting and educational experience for guests of all ages. You can explore the Geoastrophysics Museum, which houses a vast collection of scientific instruments from the 19th and 20th centuries. Don’t miss the observatory’s impressive library, where you’ll find rare books and historical documents that shed light on the rich history of Greek astronomy. A special highlight is the original 16cm telescope housed under the dome of the Sina building, used by Julius Schmidt, the third Director of the Observatory, to create the most accurate map of the Moon in the 19th century.

Must-See: The Doridis Telescope
No visit to the National Observatory of Athens is complete without exploring the Doridis Telescope. The telescope is housed in a round structure near the main building. Are you ready to explore the stars? Evening tours allow all visitors to gaze through the telescope’s lens at the night sky, creating an unforgettable experience for stargazers.

Historical Facts and More

A Monumental Beginning
The National Observatory of Athens owes its existence to Baron Sinas, a prominent Greek philanthropist. The son of a wealthy family that founded the Bank of Austria and Europe’s first railroad, Sinas generously funded the observatory's construction, which was completed in 1845. Designed by the renowned Danish architect Theophil Hansen, the main building was shaped like an "X", with each wing perfectly aligned with the four points of the horizon. This harmonious design emphasised the observatory's scientific precision and its connection to the natural world.

Why It's Important
As the first research centre in Greece and Southeastern Europe, the National Observatory has been a beacon of scientific discovery for nearly two centuries. From the moment it opened, the observatory began shaping the future of Greek astronomy, with the installation of Greece’s first telescope in 1902.

Fun Fact: Setting the Time for Greece
Did you know that until the mid-1960s, the official time in Greece was set by the observatory? Using the Sygrou Telescope, astronomers would determine the exact time.

Visiting the National Observatory of Athens offers a unique blend of science, history, and breathtaking views. From its storied beginnings in 1842 to its ongoing contributions to modern research, this iconic venue invites you to explore the mysteries of the universe. Whether you're peering through the Doridis telescope or browsing ancient celestial maps, a trip to the NOA promises an unforgettable journey through time and space.
