Gardoš (Serbian Cyrillic: Гардош; Hungarian: Gárdos) is an urban neighborhood of Belgrade, the capital of Serbia.

Located on the slopes of the hill of the same name, with its tower and preserved old architecture, Gardoš is the major historical landmark of Zemun.

Gardoš rises on the right bank of the Danube and is the natural lookout to the area across the river (Crvenka section of the Pančevački Rit in the municipality of Palilula).

Modern area of Zemun's Donji Grad was regularly flooded by the Danube and the water would carve canals through the loess.

Additionally, this area is known for lagums, a vast network of underground corridors, which were used for supply and eventual hiding and evacuation.

In the previous centuries, settlers left many vertical shafts which ventilated the lagums, drying the loess and keeping it compact.

[1] Archaeological surveys showed that the area of the modern hill was almost continually inhabited during the past millennia, as the remains from the Neolithic, Eneolithic and Iron Age (the Celts) have been found.

The cliff-like ending section of the former Bežanija Loess Ridge was suitable for habitation for several reasons: it was an excellent natural lookout as the surrounding region is mostly flat; the land, prior to full urbanization, was fertile; elevation above the Danube's bank prevented damage from the regular floods of the surrounding lowlands.

[1] For the most part, the neighborhood preserved its old looks, with narrow, still mostly cobblestoned streets unsuitable for modern vehicles, and individual residential houses.

The outer layer of the plaster completely fell off the brick walls, Because of the subsiding terrain, the southeast tower collapsed, threatening the houses below the fortress.

They are located some 2.5 m (8 ft 2 in) below the present ground level of the modern Gardoš Tower, as the terrain was additionally filled to make foundations for it.

The existing stairways which connect the tower with the city below will be expanded, while two panoramic elevators will be built, one to the Muhar (Square of Branko Radičević) and other to the Zemunski Kej, and the projected international pier on the Danube, which will be constructed in the future.

Existing towers protrude for 2 m (6 ft 7 in) above the remains of the fortress, while the fourth will be half of that height, so that the panoramic view on Zemun will be preserved.

[6] The reconstruction project of the fortress is work of architects and art conservators Aleksandra Dabižiċ, Ljiljana Konta and Rade Mrlješ.

It was mentioned for the first time in the 1578 diary of German theologian Stephan Gerlach who wrote that Serbs had a small church in the "village of Zemun", partially roofed with straw and wooden planks.

Modern clergy house, or parochial home, was built in the churchyard, on the location of the first Serbian school in this area.

By 2010, when the conservatory works began, the concrete ring girder was built on the outside, the counterweights were placed on the inside and the object was dried.

On the bequest given by his wife Marija, the church was built by the wealthy merchant Grigorije Hariš, originally from Novi Sad.

Orthodox Christians, Catholics, Muslims and Jews are buried throughout the grounds, and there are a number of solemn monuments included as well.

There is a theater called "Teatar Gardoš" but it is located south of the neighborhood, on the Masaryk square in Donji Grad.

The main cultural event is Leto na Gardošu (Summer in Gardoš), a series of mostly outdoors theatrical performances, held in July and August each year.
