Astronomical Observatories of Kazan Federal University - Russia

The property is comprised of two component parts: one in the historical centre of Kazan and the other in a forested suburban area west of the city. 

The Kazan City Astronomical Observatory, built in 1837, is located on the University campus and the building is characterized by a semi-circular façade and three towers with domes built to house astronomical instruments. 

The suburban Engelhardt Astronomical Observatory includes structures for sky observations and residential buildings, all located within a park. 

The observatories have been preserved complete with astronomical instruments and today perform mainly educational functions.
