What does the tour include?

During the tour you get to peek into the world of astronomy and learn about the eventful history of the Observatory building. Moreover, with a guide you can climb to the old astronomical observation towers in the attic. And finally, you will also see a planetarium show! In the planetarium we will experience one fast-forwarded "night", learn to identify constellations and get to see how the night sky moves. The normal tour takes 1 hour. However, you can customize your tour by for example reserving more time for the temporary special exhibition or by leaving out some of the topics.

Please note that the towers are not heated, and you can only reach the planetarium by going outside. There is an accessible entrance to the floor for exhibitions and booked venues (unfortunately not to the towers or the planetarium). Tours can be arranged in Finnish, Swedish or English.

PLEASE NOTE! Helsinki Observatory does NOT arrange stargazing shows (observations through telescopes). For this activity, please contact Ursa Astronomical Association (tel. +358 9 684 0400).
