The Astronomical Facilities of NOA at Thission & Penteli

Α. The Visitor Center in Thission is housed in the historic Sinas building, situated on the hill of the Nymphs, just across from the Acropolis and next to the hill of Pnyx. It includes  the following facilities of the National Observatory of Athens:

  • The Museum of Geoastrophysics on the hill of the Nymphs: this features the historical library of the National Observatory of Athens, the Room of Time, where the first meridian telescope and the chronometers of the Observatory are exhibited, a room with a collection of scientific instruments of 19th and 20th centuries and an educational replica of the Antikythera Mecanism.
  • The historic telescope “Dimitrios Doridis” on the hill of Pnyx that is used for stargazing during the open nights dedicated to the general public.
  • The tranquil gardens of the observatory, where educational and cultural events are presented, mainly at summertime.


Β. The Penteli Visitor Center is located in Penteli Astronomical Station around 15km from the center of Athens and consists of two historical buildings hosting three telescopes that facilitate outreach activities and are open to the general public since 1995.  

A Newall dome and a refractor telescope were originally constructed in 1869. The 14-meter diameter dome was donated to Greece by Cambridge University and was commissioned in 1960. The sizable basement hall frequently hosts outreach activities and talks and is equipped with a complete audiovisual facility. The first floor is a place devoted to science dissemination and observations of the night sky of Northern Athens.

The second building is the oldest construction of the Penteli astronomical station featuring a much smaller 3-meter dome, home of two fully operational modern telescopes. The first one is a go-to optical 14’’ telescope aiming at the night sky and the second is a 102mm solar telescope equipped with double hydrogen filter for solar chromospheric observations. Both telescopes have greatly aided science outreach schemes at least over the last decade.

Eugenides Foundation 

The New Digital Planetarium


The New Digital Planetarium of the Eugenides Foundation is one of the biggest and best Planetariums in the world and was inaugurated in 2003, replacing the original Eugenides Planetarium established in 1966. The Planetarium today includes an amphitheater of 278 seats operating under its giant screen, a tilted 24-meter dome, featuring a state of the art, high-brightness digital full-dome projection system and undergoing regular upgrades, always following the latest technological developments.

The Planetarium operates daily offering a unique learning and immersive experience to its audience. There are many different shows available in the program for all age groups, most of which are produced inhouse. Having produced more than 35 digital planetarium shows and an equal number of illustrated books expanding on the key theme of each show, having organized numerous public lectures, events and astrophotography exhibitions, and having so far attracted an estimated 7 million visitors, the Eugenides Planetarium continues to honor the last will and testament of national benefactor Eugene Eugenides (1882-1954).

The Science and Technology Center


The Eugenides Foundation’s new Science and Technology Centre opened its doors to the public in December 2018.

The aim of the Science and Technology Centre is to promote scientific education, encourage deep experiences of natural phenomena, enhance learning through interaction and engagement, introduce new scientific concepts, communicate the social and personal value of science and showcase cutting-edge scientific and technological developments.

Visitors have an opportunity to handle and control all 57 interactive exhibits covering a wide range of Science and Technology Fields, attend covering Physics, Chemistry and Biology in our fully equipped auditorium or join us in building and programing robots in our specially designed workshops.

The Science and Technology Centre offers new learning approaches that provide  opportunities for students and the general public to actively engage in science. Learning is a complex, contextual, participatory, experiential and visitor-centred process that involves more than just acquisition of facts. For this reason, the Science and Technology Centre responds to a clearcut pedagogical position based on the belief that people learn by doing and that the practice of live inquiry and discovery is fundamental in the learning process.

With 57 mind-blowing exhibits, science shows and demonstrations to enjoy, the Science and Technology Centre, spread over three floors, offers a unique experience unlike any other. Seize the opportunity to get hands-on with real scientific phenomena.

Take a virtual tour around the premises of the Science and Technology Centre.

University of Athens Observatory 

The University of Athens Observatory (UOAO) houses a 0.4 m f/8 telescope in a 5 m dome. It has initiated operations on 29 November 1999, with scientific observations following the first days of operation. Since then, hundreds of targets have been observed photometrically and spectroscopically on an almost daily basis. In parallel, public nights, astronomical events and school visits are organized every month at the University facilities, offering a unique opportunity for visual observations by means of a modern scientific instrument. Scientific projects include long-term photometric and spectroscopic studies of eclipsing and pulsating variable stars, minor bodies in our Solar System, blazars, and several other targets of opportunity, in parallel with space telescope missions.

The telescope at UOAO participates in international, dedicated observing campaigns and is part of global monitoring networks, given that it has repeatedly and successfully delivered high quality observations in such frameworks, as well as in the frame of bilateral collaborations worldwide.

Ellinogermaniki Agogi School Observatory


The Observatory of Ellinogermaniki Agogi School in Greece ( was installed in 2007 and houses a 16’’,f/10, MEADE LX200R Schmidt-Cassegrain robotic telescope as well as two solar telescopes and smaller telescopes housed in a 12m high and 6.3m wide dome. The observatory’s unique location within the premises of a school offers to teachers and students the opportunity to actively engage with scientific research in observational astronomy as well as actively participate in outreach initiatives. Throughout its years of operation, the Ellinogermaniki Agogi School Observatory has been particularly active in the production of educational content, the organization of education and outreach activities for students, teachers and the general public both in situ and beyond of the School’s premises, at national and international level and in both astronomical and educational research.
