What is a common form of vaulting used in Romanesque buildings?

Barrel vaulting is a prominent architectural feature used in Romanesque buildings, characterized by its long, continuous arch that creates a tunnel-like structure. This technique allows for the efficient spanning of space and the creation of large inner volumes. The simplicity and strength of barrel vaults provided the necessary support for the thick, heavy walls typical of Romanesque architecture, which was known for its solid, sturdy appearance. This form of vaulting facilitated the construction of aisles and clerestories, contributing to the overall structural integrity and aesthetic of the buildings. In Romanesque architecture, the use of barrel vaults is particularly significant as it reflects the style's emphasis on stability and monumental scale.
