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.

Four panoramic telescopes are also mounted on the tower, which can be used to observe the panorama of Belgrade.

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.

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.

It is the most visited tourist attraction in Belgrade, with Skadarlija being the second.

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.
