• What is the Helsinki Observatory?

    Situated at the top of Tähtitorninvuori (Observatory Hill) in Helsinki (address: Kopernikuksentie 1), the Helsinki Observatory is the astronomy visitor’s centre of the Helsinki University Museum. It opened in late 2012. You are warmly welcome to explore our exhibitions during opening hours. By booking a guide in advance, you can also visit the observation towers and see the planetarium show. If you’re looking for a unique location for a meeting or celebration, the Observatory also has venues for hire. The Observatory also organizes many public events during the year; you can find more information about these on our website. Follow us on Facebook, Instagram and Twitter!

  • Are the Observatory premises accessible?
    The exhibitions on the main floor are accessible, as are the premises for hire (Argelander Hall and the East Rotunda). Unfortunately, the observation towers and planetarium are not.

  • What is included in a guided tour?
    During a guided tour, you will learn more about the Observatory’s rich and varied history, peek into the world of astronomy, climb into the old observation towers, and see the planetarium show. Please remember that the only way for you to visit the planetarium and towers is with a guide, which must be booked at least one week in advance.
  • Does the Observatory offer free guided tours?
    On the second Saturday of each month, a Finnish speaking guided tour is included in the entrance fee. More information (in Finnish).
  • Does the Observatory offer stargazing events?
    Unfortunately, the Helsinki Observatory does not organize stargazing events where you can look at the sky through a telescope. What this means, however, is that you can go on a guided tour regardless of the weather, and even during the day! If you’re interested in observing the night sky, you can do so at stargazing events organized by the Ursa Astronomical Association at their observatory in the Kaivopuisto park (information in Finnish). These events always depend on the weather!
  • Can I organize a birthday party at the Observatory?
    You’re most welcome to throw an astronomy-themed birthday party at the Observatory! We can organize a guided tour where you and your guests can explore the Observatory and even touch a real meteorite! Food for your guests can be ordered via the Observatory's catering and it can be enjoyed in the Observatory’s private venue for hire or in the café that is located in the west wing of the Observatory building.
  • How can I pay at the Observatory?

    You can pay for the tour and entrance fees at the Observatory’s information desk (cash or card). We can also send an invoice if needed. Our venues for hire can only be paid for with an invoice. Unfortunately, we cannot accept recreational vouchers, but admission is free with the Finnish Museum Card.
