Kale - Tvrdjava (castle),
Megdan - prostor gde se okuplja narod, biju ratnici itd.(space where people are meeting, warriors are beating...)
The most beautiful and biggest park in Belgrade, which is also the most important cultural and historical complex, in which the Belgrade Fortress stands high above the Sava and Danube confluence. The name Kalemegdan applies only to the spacious plateau surrounding the Fortress, which was turned into a park in the eighties of the XIX century. When the Fortress served as Belgrade's chief military stronghold, the plateau was a place from which the enemy was kept under observation and where preparations were made for combats. Its name derives from the Turkish words kale (fort) and megdan (field). The Turks also called it Fichir-bair, which means "the contemplation hill".
