5Built Without a Central Support Column

An engineering marvel of its time, the Bramante Staircase is constructed without a central support column. This feat was accomplished by designing the staircase in a double-helix formation, with each spiral providing structural support to the other.

The absence of a central column enhances the sense of openness and allows for an unobstructed view as one ascends or descends.
