The first castle at this site of Château de Péronne was built at the end of the 9th century by Herbert I, Count of Vermandois, to replace a royal palace that had been burned down by Vikings in 884 AD. In 1191 the castle was again made a royal domain. In 1209 the castle was completely rebuilt by Philip II of France into a more-or-less pentagonal shaped stronghold flanked by circular towers and commanded by a large circular keep.
In 1536 Péronne Castle was besieged by the troops of Charles V, the Holy Roman Emperor, led by the Count of Nassau. The siege ended without succes after 31 days but had destroyed the western part of the castle, including the keep. Later the castle was partly rebuilt and in the 17th century updated to withstand the advances in artillery.
The castle kept its military use up until 1914. In World War I, during the Battle of the Somme, Péronne Castle was almost completely destroyed. After the war it was partly rebuilt in red brick.
The Museum of the Great War (Historial de la Grande Guerre), located in the Château de Péronne, is one of the most important museums in Europe about WW I. It looks at various aspects of the war such as its causes, the everyday life of the soldiers and civilians, the social changes, the reconstruction of a battlefield, the tanks, the planes etc.
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.
