About the museum
The Observatorio was built in 1831–1834 on the top of Tähtitorninvuori (Observatory Hill), after the university had moved from Turku to Helsinki following the great fire of Turku in 1827. The building was designed by the architect Carl Ludvig Engel and by F. W. A. Argelander, professor of astronomy. Engel wanted the observatory to be an ornament of the city, and on completion it was one of the most modern astronomical research institutions of its time. The professor’s family also lived in it.
The design of the building influenced the planning of the Pulkovo main observatory in Russia in the late 1830s and later other observatories. The Department of Astronomy operated in the building until 2010, and the building was renovated in 2011–2012.
Today the Observatorio is the public astronomy centre of the Tiedemuseo Liekki (Liekki Science Museum) of the University of Helsinki. The basic exhibition on the main floor presents the universe and the history of the observatory, and the old observation towers and the planetarium can be visited on guided tours. In the Meridian Hall the large astronomical instruments are still in their original positions.
