The Château d'Eu is a former royal residence built in the 16th century to replace an earlier one purposely demolished in 1475 to prevent its capture by the English. The chapel contains the tombs of Henry I, Duke of Guise, and his wife, Catherine de Clèves, who embarked on the construction of the château in 1578. The building was completed almost a century later by the Anne Marie Louise d'Orléans, Duchess of Montpensier.
Between 1830 and 1848, the château, which had been the property of the Orléans family since its acquisition by La Grande Mademoiselle in October 1657, served as King Louis-Philippe's summer residence. Her Imperial Highness Isabel, Princess Imperial of Brazil, who brought slavery to an end in Brazil in 1888, died at the Château in 1921. Her husband was Prince Gaston, Count of Eu, a grandson of King Louis Philippe I, friend of Queen Victoria.
In 1964, the city of Eu acquired the château, in which, in 1973, it installed its City Hall and created the Musée Louis-Philippe.
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.
