The expansion of the zoo would cut the pedestrian communication between the Danube's and Sava's parts of the fortress, which was already cut in 1949 but was restored in 2009 with the reconstruction and opening of the Sava Gate. Also, it would prevent the exploration of Donji Grad, which is still largely unexplored and leave the Gate of Charles VI, a masterpiece of Balthasar Neumann, within the zoo itself. As of 2017, the zoo was not relocated but the idea of expansion was dropped, too. Gornji Grad (Горњи Град), the upper section of fortress, turned into a park, with beautiful promenades and the statue of "The Victor" (Serbian: "Pobednik"), the so-called "Roman well" (Serbian: "Rimski bunar"), actually built by the Austrians, the Popular Observatory (since 1963) in the Despot Stefan Tower, the "türbe" (tomb) of Damad Ali Pasha, Mehmed Paša Sokolović's Fountain, tennis and basketball courts, etc. Also adapted for visits is the Great Austrian gunpowder magazine, built during the Austrian occupation of Belgrade 1718–39, after they destroyed the old one during the 1717 Siege of Belgrade. They directly hit the magazine with a cannonball and the explosion which followed allowed the Austrians to capture the city. The object is located below the tall rampart. The magazine is today embellished with the artifacts from the Roman period which were discovered in or around the fortress: tombstone stelae, monuments, altars and the Sarcophagus of Jonah, which originates from the 3rd century AD. It was arranged and opened for visitors in 2014. One of the Roman marble monuments, exhibited since 2012, was the so called "Herkulanka" (after Herculaneum, where first such sculptures were discovered in the 18th century). They were usually honorary representations of important women. Estimated to be work of some local sculptor to represent one of the more important female residents of Singidunum, it was made in c.300 and was found close to the Military Museum. The represented woman is rich, in heavily draped "chiton", with the "himation" mantle wrapped over the arm and head. In May 2020, there was a break in the magazine's lapidarium, and the "Herkulanka" was vandalized and broken.
