The Pont Saint-Bénézet, also known as the Pont d'Avignon, is a famous medieval bridge in the town of Avignon. It was built between 1177 and 1185. This early bridge was destroyed forty years later during the Albigensian Crusade when Louis VIII of France laid siege to Avignon. The bridge was rebuilt with 22 stone arches. It was very costly to maintain as the arches tended to collapse when the Rhône flooded. Eventually in the middle of the 17th century the bridge was abandoned.
The four surviving arches on the bank of the Rhône are believed to have been built in around 1345 by Pope Clement VI during the Avignon Papacy. The Chapel of Saint Nicholas sits on the second pier of the bridge. It was constructed in the second half of 12th century but has since been substantially altered. The western terminal, the Tour Philippe-le-Bel, is also preserved.
The bridge was the inspiration for the song Sur le pont d'Avignon and is considered a landmark of the city. In 1995, the surviving arches of the bridge, together with the Palais des Papes and Avignon Cathedral were classified as a World Heritage Site.References:
The Baths of Caracalla were the second largest Roman public baths, or thermae, in Rome. It was built between AD 212 and 217, during the reigns of Septimius Severus and Caracalla. They would have had to install over 2,000t of material every day for six years in order to complete it in this time.
The baths remained in use until the 6th century when the complex was taken by the Ostrogoths during the Gothic War, at which time the hydraulic installations were destroyed. The bath was free and open to the public. The earthquake of 847 destroyed much of the building, along with many other Roman structures.
The building was heated by a hypocaust, a system of burning coal and wood underneath the ground to heat water provided by a dedicated aqueduct. It was in use up to the 19th century. The Aqua Antoniniana aqueduct, a branch of the earlier Aqua Marcia, by Caracalla was specifically built to serve the baths. It was most likely reconstructed by Garbrecht and Manderscheid to its current place.
In the 19th and early 20th century, the design of the baths was used as the inspiration for several modern structures, including St George's Hall in Liverpool and the original Pennsylvania Station in New York City. At the 1960 Summer Olympics, the venue hosted the gymnastics events.
