Belgrade Astronomical Observatory
The oldest Serbian Research Institute is Belgrade Astronomical Observatory . This institution is located on a hill, today known as Zvezdara (meaning: place from which you can see stars perfectly) and after many years (to be precise, 100 years later) this name began to signify big part of Belgrade, and become one of the largest municipalities in Belgrade. History of Observatory is long about 125 years. Although the first scientific discovery in the territory of Serbia was astronomical, with the independence of Turkey, this science has not developed as fast as physics, mathematics, civil engineering and medicine. Observatory is open to visitors every last Saturday of the month from 11:00 am to 3:00 pm.
