Tour Philippe-le-Bel is a medieval tower in Villeneuve-lès-Avignon which marked the French terminus of the Saint-Bénézet Bridge across the Rhone between the Kingdom of France and Papal territory of Avignon. It is named after the French king Philippe-le-Bel (Philip IV 'the Fair') who was responsible for its construction.
A tower with only two storeys was completed in 1302. In spite of protests from the Count of Provence and the population of Avignon, Philippe-le-Bel pressed ahead and built a gatehouse at the end of the bridge. The tower and gatehouse formed part of a fortress with a curtain wall that enclosed several buildings including a chapel and a residence for the châtelain. A third storey was added to the tower in the middle of the 14th century.
The Saint-Bénézet Bridge was abandoned in 1669 and the fortress then ceased to serve any useful function. The French crown continued to pay for repairs but after the French Revolution the buildings were abandoned and allowed to fall into ruins. In 1822 the town of Villeneuve-lès-Avignon decided to demolish all of the fortress except the present tower. It was listed as a Monument historique in 1862 and is now open to the public.
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.
