    Helsingin observatorio

    The thoroughly renovated Helsinki Observatory, originally designed by C. L. Engel and completed in 1834, has now reopened to the public on Tähtitorninmäki Hill. The Helsinki Observatory is a showcase for science that opens up new views on the past, present and future of astronomy. The Observatory uses the latest technology to present historical items. Exhibitions seek to illustrate and visualize information and to engage and offer insight to visitors. The goal is to provide visitors with a enriching and unforgettable experience. The Helsinki Observatory is open to all, but its primary target group are school children.

    The introduction to the world of astronomy begins in the Solar System Room and the Star Room, where visitors learn about the structure of the solar system and the universe as well as phenomena that can be observed in our sky. The Science Room exposes visitors to cutting-edge research, while the Meridian Room and the West Rotunda present the history of Finnish astronomy.

    Visitors can further enhance their experience by taking a special guided tour of the Planetarium below ground level as well as the Garden Tower and the Middle and Eastern Towers. The Argelander Hall and the East Rotunda serve as festive venues and can also be used alongside the Library for workshops and group work. The Observatory building accommodates also the offices of Ursa and the University’s Almanac Office.
