Zindan Gate (Serbian: Зиндан капија, romanized: Zindan kapija) is one of the gates in the complex of Belgrade Fortress, historical core of Belgrade, the capital of Serbia. It was built in the time when fortifications were switching from cold weapons to artillery, and when first cannons were introduced in the defense.[1] Finished between 1440 and 1456, due to its unique appearance among the fortress' gates, and the 1930s reconstruction and upgrade in the Romanticist style, the medieval barbican is one of the landmarks of the fortress, and one of its most recognizable parts.[2][3]
