Sausenburg Castle was originally the stronghold of the lords of Sausenburg, and is built on a 665 metres high hill. At the beginning of the 12th century, the area was given to the Benedictine monks of the Monastery of St Blaise. The counts of Hachberg acquired the property in 1232 from the monastery. They built the castle in order to protect the area and lived there from 1246. In 1306, the counts founded the Sausenberg dynasty. From that point on, they called themselves the margraves of Hachberg-Sausenberg.
In 1315, Liuthold II of Roetteln, the last male member of his dynasty, bestowed Roetteln to the counts of Hachberg-Sausenberg. He died in 1316. The counts of Hachberg-Sausenberg moved to Rötteln Castle and established their advocates (vogts) on the Sausenberg.
John, the last of the counts of Freiburg, bestowed his property Badenweiler to the margraves of Hachberg-Sausenberg in 1444; the merger of Badenweiler, Rötteln, and Sausenberg marked the beginning of the Markgräflerland.
In 1503, through inheritance, the Sausenburg and the Markgräflerland became part of the Margraviate of Baden. The castle was destroyed in 1678 during the Franco-Dutch War by the army of French Marshal Créquy. At this point, medieval fortifications could not survive long against the advances in artillery and siege warfare.
Today an old circular rampart, a tower and several wall segments remain of the former castle.
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.
