"barrel vault"的定义和意义

What is a "barrel vault"?

A barrel vault is an architectural feature that consists of a series of connected arches, creating a long, continuous, tunnel-like ceiling. This type of vault has a rounded shape, resembling a half-cylinder, and is often used in the construction of hallways, corridors, and large rooms. Barrel vaults provide structural strength and support, allowing for open spaces without the need for many supporting columns. They are commonly found in Roman and Romanesque architecture, giving buildings a sense of height and grandeur. The smooth, curved surfaces of barrel vaults can also enhance the acoustics of a space, making them functional as well as visually appealing.
