Gardoš (Serbian Cyrillic: Гардош, Hungarian: Gárdos) is an urban neighborhood of Belgrade, the capital of Serbia. It is located in Belgrade's municipality of Zemun. 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 is one of three hills on which the historical core of Zemun was built (other two are Ćukovac and Kalvarija). 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). Gardoš borders the neighborhoods of Gornji Grad on the northwest, Ćukovac and Muhar on the south and Donji Grad on the southeast.
For the most part, the neighborhood preserved its old looks, with narrow, still mostly cobblestoned streets unsuitable for modern vehicles, and individual residential houses. As a curiosity, almost half of the neighborhood is occupied by Zemun's largest graveyard. As a popular promenade become somewhat of a fashionable place since the 1990s, several modern restaurants were built near the top of the hill with the view on the Danube.
The major attraction in the neighborhood is the Kula Sibinjanin Janka (The tower of Janos Hunyadi) or the Millennium tower, also known as the Tower on the hill or simply the Gardoš tower. It was built and officially opened on August 20, 1896 to celebrate a thousand years of Hungarian settlement in the Pannonian plain. It was part of the massive construction effort which included buildings in Budapest as well as four millennium towers on four directions of the world. Being the southernmost city in then Hungary within the Austria-Hungary, the tower was built on the ruins of the medieval fortress on Gardoš hill which barely survived today (only angular towers and parts of the defending wall). The tower was built as a combination of various styles, mostly influenced by the Roman elements. Being a natural lookout, it was used by Zemun's firemen for decades. Today, the tower is better known after the Janos Hunyadi, who actually died in the old fortress four and a half centuries before the tower was built.
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 otudoors theatrical performances, held in July and August each year.
