Château de Sedan is a castle situated in Sedan, France, near the river Meuse. Covering an area of 35,000 square metres in its seven floors.
Around 1424, Eberhard II von der Mark built a manor with two towers around a church over a period of six years. When Eberhard died in 1440, his son Jean de la Marck began reinforcing the fortress, but it was Robert II de la Marck, the grandson of Jean, who finished the most important work. In 1530, the fortifications of the manor were modernised by the construction of a circular boulevard and terraces with cannons, thickening the 4.5-metre curtain wall by an additional 26 metres (85 ft). The bastions were added during the course of the next century, but some of them were eventually dynamited at the end of the 19th century. In 1699, the principality having been absorbed into France in 1642 (during the Thirty Years' War), and the castle having been transformed into a garrison, Vauban built the door of the Princes that was adapted to the progress of artillery. In 1822, the Church of Saint-Martin was demolished and replaced with a store for cannonballs.
On September 1, 1870 during the Franco-Prussian War, the Army of Chalons was defeated at the Battle of Sedan. Napoleon III surrendered the following day in the small neighboring city of Donchery.
The castle was used as a military hospital by the German army in World War I. Sedan was also the site of a French loss to the Germans in World War II in the Battle of Sedan (1940).
The castle was given by the French Army to the city of Sedan in 1962. Today the castle contains a hotel and a museum showing the lives of inhabitants throughout its history and the Franco-Prussian War.
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.
