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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
