The (simple or barrel) arch, the vault (or vaulted arches) and (Roman) concrete were the key elements of what historians have called the Roman architectural revolution. The arch has a strong load-bearing capacity. The vault also had a strong load-bearing capacity and is suited for the construction of large roofs. Concrete enable the construction of very large arches and vaults. Thus, the arch and vault became essential for the construction of large building and enabled the Romans to go beyond the post-and-lintel technique for enclosing spaces of the Greeks. A prime example is the Colosseum. The first three tiers of the external wall have 86 arches which support this gigantic structure and served as entrances.The seatings on the tiers were supported by vaults.
The arches also enabled the Romans to build much longer bridges which could cross much wider valleys and rivers than ever before. Trajan's bridge over the Danube was the longest bridge in the world for more than 1,000 years. If the bridges needed to be high, they could be built with two or three tiers of arches. The most notable example of this is the Pont du Gard in southern France. It has three tiers of six large arches on the first tier, eleven smaller arches on the second and 47 on the third which were 22 m (72 ft), 20 m (66 ft) and 7 m (23 ft) high respectively. In total the bridge was 49 m (160 ft) high.
Roman domes are found in baths, villas, palaces, and tombs.They usually acted as the roofs of central halls and gave them a circular structure. Concrete enabled the Romans to build domes on a monumental scale. The most famous example is the dome of the Pantheon in Rome. It has a inner circumference of 43.3 m (142 ft) and is still the largest unreinforced concrete dome in the world.
With regard to temples, the Romans built them in the style of the Greeks. They adopted the three orders (styles) for making columns, which they sued for their temples and porticoes: Dorian, Ionian and Corinthian. They also developed the composite style, which combined elements of two orders. Apart from the above, Roman architecture was essentially Roman. The Romans effected what historians called the Roman architectural revolution. This was based on (Roman) concrete and the first large scale use of monumental barrel (or simple) arches and the vaulted arch (or vault). Concrete provided a tough, durable and cheaper material. The arch has a great load bearing capacity and the vault is suited to sustain large roofs. These elements enabled the Romans to go beyond the post-and-lintel method of enclosing space of the Greeks. It made the construction of such a gigantic structure as the Colosseum possible. The arch was also used for bridge construction and enabled the Romans to build much longer bridges.
Washington DC has many buildings that have been influenced by the Romans. The arch, vault, and dome are all from the Romans.
The Romans were first to fully appreciate the advantages of the arch, the vault and the dome. The arch has a strong lad bearing capacity. The Etruscans invented the simple barrel arch and Pergamon invented the vault (adjacent arches which are assembled side by side) which has an even greater load bearing capacity and whose structure is also suited to support large roofs. The Romans invented segmental arch as they realised that an arch did not have to be a semicircle. The Roman used the arch to build gates, aqueducts, bridges which were much longer than before and could cross much wider rivers and valleys. The arches, especially the vault, became essential for the construction of large scale buildings. The Romans also developed a new and much stronger type of concrete which was as resistant as modern concrete and also set underwater (this enabled them to build much bigger docks for ports). However, it was not as fluid as modern concrete and had to be layered by hand. The arch, the vault and concrete were what made the construction of such a massive structure as the Colosseum possible. Concrete was also used to build domes. The Pantheon (a temple which has been turned into a church) in Rome is still the largest unreinforced concrete dome in the world. Often the Romans used a mixture of stone, brick and concrete (for the Colosseum stone and concrete were used). The Romans also used columns to build temples and porticoes. The Romans built scaffolding around what they were building. They adopted the cranes of the Greeks and massively improved on them. The simplest one was the trispastos, which had of a single-beam, a winch, a rope, and a block with three pulleys. It had had a mechanical advantage of 3:1, and single man operating the winch could raise 150 kg. The pentaspastos had five pulleys and the polyspastos had a set of three by five pulleys with two, three or four masts. The latter was worked by four men at both sides of the winch and could lift 3,000 kg. When the winch was replaced by a treadwheel, the load could be doubled to 6,000 kg with only half the crew, because the treadwheel had a larger diameter and thus a much bigger mechanical advantage.
The vault, or vaulted arch is a structure made up of two or four intersecting arches. There Romans had two types: the groin arch, which is formed by two to four intersecting barrel (simple) arches and the rib arch, where the intersecting arches are of different diameter. This structure has an even greater load-bearing capacity than the simple arch. It is suited for supporting large roofs.
Much of the technology had been developed before the Pax Romana. The three elements of the Roman architectural revolution (Roman concrete, the arch and the vault), the hypcaust (the system of underfloor heating), the arched bridges, the aqueducts and the stone-paved roads were developed before the Pax Romana. The ballista (a crossbow-like catapult), the groma (a surveying instrument) and the siege machines of the Greeks had already been adopted. What happened during the Pax Romana was that there was large scale construction of infrastructure (roads, bridges, aqueducts, ports and dams) and public buildings using new technologies which had already been developed, rather than further technological innovation. The use of these technologies was pushed further with the construction of ambitious projects, such as the Colosseum, the Pantheon and the bridge over the River Danube), New and more efficient types of ballistas were also developed.

Roman architects frequently used the arch, vault, and dome in construction because these structural elements allowed for the creation of larger and more stable spaces than traditional post-and-lintel systems. The arch distributes weight more evenly, enabling the construction of monumental structures like aqueducts and amphitheaters. Vaults and domes further expanded interior spaces and provided aesthetically pleasing, open designs, as seen in famous structures like the Pantheon. This innovative use of geometry and engineering facilitated the grandeur and durability characteristic of Roman architecture.

In the game "Monkey Go Happy," the vault code is a sequence of numbers that players must input to unlock the vault and progress in the game. The vault code is randomly generated in each level, so there is no universal code that applies to all players. To find the vault code, players must carefully explore the level and solve puzzles to uncover the code.

A bank vault door typically weighs between 10,000 and 25,000 pounds, depending on its size, thickness, and materials used in its construction.
vault, dome
The barrel vault is primarily associated with Romanesque architecture, characterized by its semi-circular shape and solid, heavy construction. In contrast, the ribbed vault is a feature of Gothic architecture, allowing for greater height and more complex designs through the use of pointed arches and structural ribs. Both vault types reflect the technological advancements and aesthetic goals of their respective architectural styles.
The main features of Roman architecture were the arch, the vault and concrete.
There are 7 vaults as follows: Vault 87 Vault 92 Vault 101 Vault 106 Vault 108 and Vault 112
