Who Invented the Spiral Staircase?
The spiral staircase, like many other modern designs, has its roots in history. While spiral stairs have many uses, and are often pleasing to the eye of a designer, they were created hundreds of years ago as part of a last ditch effort to a very serious problem.

What is a Spiral Staircase?
-
A spiral staircase, by definition, is a staircase with a central pole or post in which stairs are set out in a spiral. As the stairs progress up the pole in a screw-like pattern, elevation is achieved.
When Were Spiral Stairs Invented?
-
Though an exact date isn't known, the spiral staircase came into common use during the Middle Ages (between the 5th and 12th centuries) as a way to reach the top of towers, often held inside a castle's outer walls.
-
Purpose
-
Though spiral stairs have several benefits, their use in castles and towers was defensive. Those attempting to storm a tower would find themselves at a disadvantage. The defenders could use their sword arm more readily than the attackers (if both men were right handed), and the narrow stairs forced one-on-one combat.
Modern Uses
-
Today, spiral staircases are used more for different, practical purposes. They maximize floorspace, are aesthetically appealing, and often make efficient use of areas in smaller homes and condominiums.
Varieties
-
Though the first spiral staircases were made of stone, the technology has advanced to include wood, metals and combinations of many different materials. Like most other furnishings, a spiral staircase can be customized, depending on a person's budget and desires.
