Topčiderski Park, the oldest in Belgrade, is located on the lush Topčiderski hill, in whose greenery the Topčiderska river also drowns. In this idyllic landscape, the Serbian prince Miloš Obrenović built a konak (Miloš's konak) for himself, which later became the Court of the Principality of Serbia, and today part of the History Museum of Serbia. It is interesting that the key that opens the main door is 30 cm long because the door is so thick.
