How many steps lead up to the Parthenon's stylobate?

Three steps lead up to the Parthenon’s stylobate: the temple’s raised platform is a three-stepped crepidoma, with the stylobate forming its uppermost level.

In Greek architecture, the stylobate is technically the top step on which the columns stand. The lower steps are often described as part of the stereobate or, more broadly, the crepidoma. In everyday descriptions, however, people commonly call the entire three-level base the Parthenon’s steps or stylobate platform.

The Parthenon’s platform was built from carefully fitted stone and measures roughly 69.5 metres by 30.9 metres at the top. Each of the three levels is substantial, so the building rises visibly above the surrounding Acropolis surface. Small intermediate steps were provided at the centre of the eastern and western sides to make access easier.

The base is not perfectly flat or geometrically ordinary. Its horizontal surfaces curve gently upward toward the centre, an optical refinement intended to prevent the long lines from appearing to sag. Similar visual corrections affect the columns and entablature, making the temple look more regular from a distance.
