List of ancient spiral stairs

The list of ancient spiral stairs contains a selection of Greco-Roman spiral stairs constructed during classical antiquity. The spiral stair is a type of stairway which, due to its complex helical structure, has been introduced relatively late into architecture. Although the oldest example dates back to the 5th century BC, it was only in the wake of the influential design of the Trajan's Column that this space-saving new type permanently caught hold in Roman architecture. The construction of spiral stairs passed on both to Christian and Islamic architecture.
