The Château de Pierre-Percée ('pierced rock castle') in the commune of Pierre-Percée. The site in the early 12th century was in possession of Agnès, countess of Bar and widow of the count of Langenstein. She married Hermann II, Count of Salm and son of Hermann I, King of Germania (Eastern Francia). A well dug (~30 m) into the rock gives the village and the castle their name. The territory, which included the towns of Badonviller (which became the capital of the county) and Blâmont, became for several hundred years part of the hereditary property of the Counts of Salm. Around 1134, Hermann II went to war allied to the Duke of Lorraine against the Count of Bar and Stephan of Bar, the Bishop of Metz, himself a member of the Bar family. Hermann was killed on the battlefield outside the Château de Frouard. The castle at Pierre-Percée was besieged for a year and fell into the hands of the bishop of Metz with the death of Hermann's eldest son.
The castle was not besieged again until the Thirty Years' War (1618-1648) when, being deserted, it was destroyed by Franco-Swedish troops.
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.
