vault, in building construction, a structural member consisting of an arrangement of arches, usually forming a ceiling or roof. Roman architects discovered that two barrel vaults that intersected at right angles formed a groin vault, which, when repeated in series, could span rectangular areas of unlimited length.
What are Roman vaults used for?
Vaults, which are also called vault bays, are like bays in being the areas between supports. Vaulting refers to the use of a system of vaults, which was the very essence of Roman architecture. Vaulting enabled the Romans to build such spectacular structures as the Pantheon and the Colosseum, which are both in Rome.
Did the Romans invent vaults?
The Roman arch also caused the Romans themselves to make further architectural developments. They combined arches to form ceilings or roofs called vaults. The Romans also used the principles of the arch to form a hemispherical ceiling or roof called a dome.
Why were vault arches added?
However, arches may be introduced in the supporting walls and transverse ribs may be inserted in the vault to concentrate thrust at a few strongly buttressed points, thereby permitting a reduction of weight and thrust in the segments of vaulting between the ribs.
How did they build a vaulted ceiling?
Vaulted ceilings can be constructed by either stick-framing, which means attaching each joist and rafter individually, or by setting roof trusses that come engineered from a truss manufacturer with the vaulted space already accounted for.
What are the disadvantages of a barrel vault?
The disadvantage of a barrel vault, however is that it exerts thrust the same way the arch does. Meaning, the vault exerts an outward thrust and thus must be buttressed along the entire length. This characteristic prevented the use of large windows as well as prevented easy circulation.
Who invented vaults?
The vaulting technique of the Etruscans was absorbed by the Romans, who started in the 1st cent. AD the development of a mature vaulting system. Casting concrete in one solid mass, the Romans created vaults of perfect rigidity, devoid of external thrust, and requiring no buttresses.
How did the Romans transport water uphill?
The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueducts moved water through gravity alone, along a slight overall downward gradient within conduits of stone, brick, or concrete; the steeper the gradient, the faster the flow.
How good was Roman Steel?
The quality of Roman swords varied as much as the quality of medieval swords – from very poor to very good. There are examples of gladiuses with steel edges welded onto softer cores.
What is the definition of a Roman vault?
Roman vaults were the basis on which more complex and varied forms were developed in the Middle Ages. The tunnel (or barrel) vault spans between two walls, like a continuous arch.
What is a Roman barrel vault?
Barrel vault. Barrel vaults are known from Ancient Egypt, and were used extensively in Roman architecture. They were also used to replace the Cloaca Maxima with a system of underground sewers. Other early barrel vault designs occur in northern Europe, Turkey, Morocco, and other regions.

What is a Roman groin vault?
The groin vault heralded many of Rome’s greatest building projects. Today, one of the most important places you can see groin vaults is at the Colosseum. Forming a continuous corridor around the arena, the groin vaults allowed the high ceilings and monumental stadium.
