Origins of the Château Bilquin de Cartier can be traced back to the around 1635, when the Honoré family built a castle on the Sambre river bank. The place had formerly been occupied by a seigneurial manor which was destroyed on 21 July 1554.
In 1667, the unfinished Spanish fortress of Charleroy was captured by Louis XIV's troops during the War of Devolution. As the castle in Marchienne was located in neutral territory (under authority of the Prince-Bishopric of Liège), it was used as a hospital for both French and Spanish soldiers.
In 1695, the castle was bought by Guillaume de Bilquin, a wealthy forge owner, who completes and enhances it. Later the castle became the property of the Cartier de Marchienne family. It was severely damaged by a fire in 1932, and bought over by the municipality of Marchienne-au-Pont in 1938, ending more than two centuries of ownership by the Cartier family.
The castle today hosts a public library on the ground floor (Bibliothèque Marguerite Yourcenar), and administrative services of the Walloon region on the first floor.
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.
