Niš Fortress

Niš Fortress (Нишка тврђава / Niška tvrđava) is a fortress in the city of Niš, Serbia. It is a complex and important cultural and historical monument. It rises on the right bank of the Nišava River, and is over two millennia old.

The extant fortification is of Turkish origin, dating from the first decades of the 18th century (1719–1723). It is well known as one of the most significant and best preserved monuments of this kind in the mid-Balkans. The Fortress was erected on the site of earlier fortifications - the ancient Roman, Byzantine, and later yet Mediaeval forts. The Fortress has a polygonal ground plan, eight bastion terraces and four massive gates. It stretches over 22 ha of land. The rampart walls are 2,100 m long, 8 m high and 3 m thick on the average. The building stone, brought from the nearby quarries, was hewn into rather evenly-shaped blocks. The inside ofhe rampart wall was additionally fortified by a wooden construction, santrač, and an additional bulwark, trpanac. On the outside, the Fortress was surrounded by a wide moat, whose northern part has been preserved to our days. Beside the massive stone rampart walls, the southern Stambol Gate and the western Belgrade Gate are pretty well preserved. Partly preserved are the water gates, while there are only remains of the northern Vidin Gate and the south-east Jagodina Gate. With a complete reconstruction of all the gates, Niš Fortress would once again become, architecturally and functionally, a closed fortification system.

Far into the fortress, there is a weather station, that provides forecasts for the city of Niš.

Since 1966, the fortress is the location of the Niš Film Festival.
