Observatory tour

On the observatory tour you can explore the rich history of the Tuorla Observatory and at the same time learn a great deal about modern astronomy. The tour includes a visit to Finland’s largest telescope, the rock tunnel that runs through Tuorla’s Laukkavuori — which served as Yrjö Väisälä’s optical laboratory and where some of the world’s most precise mirrors and lenses are still ground — and, when possible, the radio telescope and Opteon Ltd’s optics workshop.

Tours are always tailored to the visitors, so by the end the secrets of the universe will feel a little more familiar both to preschool children and, for example, conference guests. Welcome to learn more about our vast universe and to hear how Finnish astronomy and engineering have played a part in unlocking the mysteries of the cosmos.
