The History of Spiral Staircases
The origins of spiral staircases date back to ancient times. They were commonly used in medieval castles and religious structures, providing a strategic advantage in battles while also enhancing the grandeur of buildings.
Ancient Civilizations
- Mesopotamia and Egypt: Early versions of spiral staircases were found in temples and palaces.
- Greece and Rome: Greek and Roman architecture featured spiral staircases in lighthouses, such as the famous Pharos of Alexandria, and amphitheaters.
Medieval Period
