Damat Ali-Paša's Turbeh

The siege of Belgrade was a successful attempt by Austrian troops under the command of Prince Eugene of Savoy to capture the strategically important city of Belgrade from the Ottoman Empire. It took place during the Seventh Ottoman–Venetian War (1714–1718), barely a year after the Austrian victory at the Battle of Petrovaradin (Peterwardein). The Austrians routed the Ottoman relief army under Grand Vizier Hacı Halil Pasha on 16 August. As a consequence, the Belgrade garrison, deprived of relief, surrendered to the Austrians on 21 August. The Ottoman Sultan Ahmed III sued for peace, resulting in the Treaty of Passarowitz a year later, which completed the transfer of the remainder of Hungary, the Banat and the city of Belgrade into Austrian hands.

The Belgrade Fortress (Serbian Cyrillic: Београдска тврђава, romanized: Beogradska tvrđava), consists of the old citadel (Upper and Lower Town) and Kalemegdan Park (Large and Little Kalemegdan) on the confluence of the Sava and Danube rivers, in an urban area of modern Belgrade, Serbia. Located in Belgrade's municipality of Stari Grad, the fortress costitutes the specific historical core of the city. As one of the most important representatives of Belgrade's cultural heritage, it was originally protected right after World War II, among the first officially declared cultural monuments in Serbia. The fortress was declared a Monument of Culture of Exceptional Importance in 1979, and is protected by the Republic of Serbia. It is the most visited tourist attraction in Belgrade, with Skadarlija being the second. Since the admission is free, it is estimated that the total number of visitors (foreign, domestic, citizens of Belgrade) is over 2 million yearly.

Mehmed Paša Sokolović's Fountain (Serbian: Чесма Мехмед-паше Соколовића, romanized: Česma Mehmed-paše Sokolovića) is an Ottoman era fountain in Belgrade. It is located next to the Defterdar's Gate near the northwestern wall of the Upper Town of Belgrade Fortress. Evliya Çelebi states that the fountain was erected in 1576/77, during the lifetime of Grand Vizier Меhmed Paša Sokolović and it is his only surviving endowment in Belgrade. The precise position of the fountain does not appear in any cartographic sources until the 17th century. The earliest sketch dates back to a plan from the National Library in Paris from the early 17th century, in which the fountain was presented as a rectangular structure with three free sides.

The Military Museum (Serbian: Војни музеј, romanized: Vojni muzej) is a museum located in Belgrade, Serbia. Founded in 1878, the museum has over 3,000 ancient and modern items. These include Roman swords and helmets, Greek helmets and daggers, Serbian heavy knight's armor, axes, shields, helmets, crossbows, armoured gloves, as well as Western medieval weapons. There are also more modern guns, firearms, and elements of soldier's uniforms and equipment. Dioramas, plaques, and displays illustrate the use and historical context of the museum's collection. Inside the museum's main building, the exhibits are found in a single long hall progressing from ancient through medieval and then towards modern. All exhibits are labeled in the Serbian Language in both Cyrillic and Latin, as well as English. Outside the museum's main building, there are numerous tanks, howitzers, and armoured cars of many types. Some were acquired during World War II, when they were captured by the Red Army and Yugoslav Partisans from retreating Nazi and Axis forces (Belgrade Offensive). These decommissioned tanks and artillery pieces line the walls and paths leading into the Military Museum from two directions. Recent exhibits address NATO actions against Serbia in 1999, including the controversial use of cluster bombs, depleted uranium, and graphite bombs, some of which are claimed to be in violation of international law. A well-known exhibit features parts of a US F-117 stealth aircraft which was downed by a Serbian S-125 Neva/Pechora. The Military Museum is located inside the walls of the historic Belgrade Fortress, situated at the confluence of the Sava and Danube rivers. The Belgrade Fortress is located within a popular park known as the Kalemegdan Park, near the center of the city.
