A barrel vault refers to a long, tunnel-like roof formed by a single curved surface that runs the length of a space. This continuous arch shape distributes weight along the walls and creates a straight, elongated form ideal for corridors and aisles in ancient and medieval buildings. The other terms describe different vaults: a groin vault comes from the intersection of two barrel vaults at right angles, producing groins; a dome vault is shaped like a hemisphere crowning a space; and the phrase vaulted tunnel isn’t the standard architectural term, though it conveys the same long, tunnel-like quality. The description matches the barrel vault most precisely.
