Welcome to Helsinki Observatory!

Photo Timo Huvilinna.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 building houses the Centre for Astronomy, a visitor centre of the Helsinki University Museum, where school children and other visitors can learn about space, astronomy and the history of astronomy.

The Helsinki Observatory collaborates closely with the Ursa Astronomical Association, the discipline of astronomy and LUMA Centre of the University of Helsinki as well as the City of Helsinki. The Observatory building accommodates not only the Centre for Astronomy, but also the offices of Ursa, the University's Almanac Office and Café Tiedekahvila.
