In 1184 Baldwin V, Count of Hainaut, built the first castle on the current site in Écaussinnes. The lords of Écaussinnes and their heirs the de Lalaings altered the original structure several times over the centuries.
In 1450 Marie de Lalaing married Jean II de Croÿ, descendant of the Counts (later Princes) of Chimay. By a quirk of inheritance, the castle later became the property of the Lalaing family again. They sold it in 1642 to the van der Burcht family.
In the 18th century the interior was redecorated with Rococo elements in the first floor of the Gothic hall.
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.
