A Step Up

Short answer: Stairs began as steps cut into hillsides and rock. Romans built more elaborate stairs with stone and concrete; medieval castles used spiral staircases, which tradition says favored right-handed defenders; and Renaissance architects made grand decorative staircases.

Steel and reinforced concrete later allowed floating and helical designs. The footage is a computer-generated sequence of staircases through the ages.

Video transcript: A Step Up: Spiral Stairs in Castles Helped Defenders

Did you know, the evolution of stairs spans from basic, functional stone steps in ancient civilizations to today's intricate artistic designs. Early staircases were cut into hillsides or rock, later evolving with the Romans, who used concrete to build more elaborate structures. In medieval castles, spiral staircases provided a tactical advantage during battles, while the Renaissance saw the rise of grand, decorative staircases in public and private buildings. Modern materials like steel and concrete have transformed stairs into architectural statements, enabling innovative designs like floating or helical staircases, which blend form and function in unique ways.
