Nebotičnik
Nebotičnik is a high-rise building located in the centre of Ljubljana, Slovenia. On completion in 1933, it was the tallest building in the Kingdom of Yugoslavia, and the ninth-tallest in Europe. There are shops on the ground and first floors, and offices on floors two to five. The sixth to ninth floors are private residences, and a café, bar and observation deck are located on the top three floors. The entrance on the ground floor leads to a lobby from which the upper storeys are accessible by elevator or by this Art Deco spiral stairway at the centre of the building.Photograph credit: Petar Milošević
