Ružica Church (Serbian Cyrillic: Црква Ружица, romanized: Crkva Ružica, lit. ''Little Rose Church'') is a Serbian Orthodox church located in the Belgrade Fortress, in Belgrade, the capital of Serbia. Original church was built in the early 15th century, while the modern one was adapted in 1869 and fully reconstructed in 1925. It is dedicated to the Nativity of Mary. With its location within the fortress and water spring of Saint Petka, constant crowds of visitors especially on Saint Petka's feast day, and unorthodox appearance, it is considered one of the "best loved churches among the adherents".

The Chapel of Saint Petka in Belgrade is a chapel, erected over a sacred spring, and dedicated to Saint Petka. It is located at a way connecting the upper and the lower city of the Belgrade Fortress, in proximity of the Ružica Church, with the spring being in the very altar of the chapel. The today's chapel is built in 1937 after a project of the architect Momir Korunović. Its inner walls and vaults are covered by mosaics done by painter Đuro Radulović in 1980-83.

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.

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.

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 Kalemegdan Park (Serbian: Калемегдански парк / Kalemegdanski park), or simply Kalemegdan (Serbian Cyrillic: Калемегдан) is the largest park and the most important historical monument in Belgrade. It is located on a 125-metre-high (410 ft) cliff, at the junction of the River Sava and the Danube. Kalemegdan Park, split in two as the Great and Little Parks, was developed in the area that once was the town field within the Belgrade Fortress. Today residents often erroneously refer to the entire fortress as the Kalemegdan Fortress or just Kalemegdan, even though the park occupies the smaller part, especially of the historical fortress, and it is some two millennia younger. The fortress, including the Kalemegdan, represents a cultural monument of exceptional importance (from 1979), the area where various sport, cultural and arts events take place, for all generations of Belgraders and numerous visitors of the city.

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.
