Built on top of a rocky outcrop overlooking the village and the Semois Valley, the medieval ruins of Herbeumont castle offer a splendid panorama of the river and its meanders.
The first stones of the fortress were laid by Jean of Rochefort, of the House of Walcourt. From one century to another, it will belong to other families: Orgeo, Marck-Rochefort, Stolberg and Löwestein.
Building it on this peak meant the castle could only be accessed on one side. In the 15th century, towers were added and ramparts strengthened. It was destroyed by French troops on August 21, 1657.
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.
