Roman stair的意思

"Roman stair" is a term used in architecture to describe a type of staircase that has a series of steps on one side and a single continuous flight of steps on the other side, with no central handrail. This design is also known as a "Roman-style" or "Romanesque" staircase. The term is derived from the ancient Roman architecture, where such staircases were commonly used in public buildings, such as amphitheaters and baths.

In a Roman stair, the steps on one side are usually wider and shallower than the steps on the other side, which are narrower and steeper. This design allows for a greater number of people to ascend or descend the staircase at the same time, as the wider steps can accommodate more foot traffic. The continuous flight of steps on one side is often used as a seating area or a place to rest, which is why Roman stairs are sometimes referred to as "bench stairs."

Roman stairs were popular in medieval Europe, particularly in Romanesque and Gothic architecture, and they continue to be used in modern architecture for both functional and aesthetic purposes. They are often found in historic buildings, museums, and public spaces, where their unique design adds a touch of grandeur and elegance to the structure.
