The Tartu Observatory is the largest astronomical observatory in Estonia. It is located on the Tõravere hill, about 20 km south-west of Tartu in Nõo Parish, Tartu County. The old Tartu Observatory is known internationally for its connection to Friedrich Georg Wilhelm von Struve and the Struve Geodetic Arc, of which it is the first reference point.
The observatory has two main telescopes. The 1.5 metre Cassegrain reflector, which is the largest optical telescope in Northern Europe, is used for spectroscopic observations. The second telescope is a 0.6 metre reflector for photometric observations. There is also a pitch for a collection of meteorological instruments on the observatory grounds.
