Arles Roman Theatre was built in the time of Augustus and. It had a capacity of seating for 8,000 on 33 tiers of steps. In the early Middle Ages the theater was used as a quarry, and with the material it provided the town wall was erected. Of the rear wall of the stage only a few stumps of pillars and two more or less complete columns remain. Since the theater is now used again during the summer it is protected on the outside by screens and the interior is somewhat spoiled by the necessary technical apparatus.
Most of the relics brought to light during excavation can be seen in the Arles Museum of Antiquity - the most important of these is the 'Venus of Arles', a representation of the goddess Diana, which was discovered near a fountain in 1651 and is now in the Louvre in Paris.
The Roman Theater has been listed as World Heritage Sites since 1981. Arles Roman Theater is now a monument to visit and a place of concerts and events.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
