The building of the Town Hall in Arles located in Republic Square, opposite the Cathedral of St. Trophime. Construction of the town hall began in the middle of XVII century and was completed in 1676. The work was done about two decades, and as the construction site was chosen the place where the house was located communes of earlier construction.
By decision of the members of the city council building of the town hall was located between the palace and Podesta Clock Tower. The palace was built in the XIII century and is considered the oldest building in the city local government. It is now housed offices and municipal officials. The Clock Tower was built in the middle of the XVI century, typical of the Renaissance style and is now seen as part of the town hall, in spite of the different stylistic decision - Town Hall building itself was erected in the classical tradition.
One of the leaders of works on construction of the town hall was the architect Jules Hardouin-Mansart, the court architect of Louis XIV. By the way, Jules Hardouin-Mansart is the grandson of another architect, François Mansart, who invented the "mansarovu" or simply the roof loft.
The building is a three-storey palace hall decorated with columns and a pediment with the image of the sun - a symbol of King Louis XIV. Sculptures in the interior of the town hall were created by local sculptor Jean Didier (eg, stone lions on the stairs of Honor), other decorative elements have also been made by several artists. Interior decorating the town hall were partially decorated during the time of the French Revolution, but some elements (wood panels of the XVIII century) are preserved.
Under the city hall are kriptoportiki - underground galleries with arched spans, which were built, most likely, the Romans. Part of the underground galleries used as a prison.
