French architecture ranks high among France's many accomplishments. Indications of the special importance of architecture in France were the founding of the Academy of Architecture in 1671, the first such institution anywhere in Europe, and the establishment in 1720 of the Prix de Rome in architecture, a competition of national interest, funded by the state, and an honor intensely pursued.
The architecture of Ancient Rome at first adopted the external Greek architecture and by the late Republic, the architectural style developed its own highly distinctive style by introducing the previously little-used arches, vaults and domes. A crucial factor in this development, coined the Roman Architectural Revolution, was the invention of concrete. Social elements such as wealth and high population densities in cities forced the ancient Romans to discover new (architectural) solutions of their own. The use of vaults and arches together with a sound knowledge of building materials, for example, enabled them to achieve unprecedented successes in the construction of imposing structures for public use.
Notable examples in France during the period are Alyscamps in Arles and Maison Carrée in Nîmes. The Alyscamps is a large Roman necropolis, which is a short distance outside the walls of the old town of Arles. It was one of the most famous necropolises of the ancient world. The name is a corruption of the Latin Elisii Campi (that is, Champs-Élysées or Elysian Fields). They were famous in the Middle Ages and are referred to by Ariosto in Orlando Furioso and by Dante in the Inferno. The Alyscamps continued to be used well into medieval times, although the removal of Saint Trophimus' relics to the cathedral in 1152 reduced its prestige.
