The Fort de Condé, or Fort Pille, is a fortification of the Séré de Rivières system, built in France between 1877 and 1883 to defend the area between Soissons and Laon. It is located on the heights of the confluence of the Aisne and the Vesle near the communes of Condé-sur-Aisne and Chivres-Val. Although the fort was considered obsolete at the start of World War I, its command of strategic ground made it a coveted objective throughout the war, changing hands several times. Following the war it was used in support service before its abandonment and purchase by a local community. It has been under preservation since 1979 and may be visited.
The five-sided masonry fort was built by Dollot and Fortier at a cost of 1,850,000 francs-d'or. The fort covered 13 hectares and could accommodate almost 650 men and 20 officers. An infirmary for 80 invalids was also provided, as well as stabling for 12 horses, powder and ammunition magazines, a forge, a workshop and two wells. The fort featured two Mougin casemates mounting 155mm guns, as well as an initial18 guns on the rampart and 8 guns in a separate battery. Two casemates in the main fort were planned to provide indirect fire. The fort is roughly pentagonal, and features two double caponiers and a single caponier. One of the double caponiers provides covering fire to the fort's entrance.
The site is used for exhibitions, theater and son et lumière shows.
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.
