Beginning in 982 the Sargans region was part of the lands of the Counts of Bregenz. In 1160, the male line of the Counts of Bregenz died out. Count palatine Hugo of Türbingen inherited most of their lands, through his wife Elisabeth. His son, Hugo, inherited the Bregenz lands around Lake Constance, including Sargans. This Hugo, who adopted the name Montfort und Werdenberg built or expanded Sargans Castle before his death in 1228. Excavations around the oldest part of the castle show that there was an earlier fort or castle, but nothing is known about that building. Hugo built the large bergfried, expanded the walls to the west and may have built a palas on that side of the castle.
In the mid-13th century the Montfort und Werdenberg lands were divided between Hugo of Werdenberg-Heiligenberg and his brother Hartmann of Werdenberg-Sargans. Hartmann took up residence in the castle and probably expanded the palas. The castle was first mentioned in 1282. Over the following century the wealth and lands of the Counts of Werdenberg-Sargans were divided over and over again between descendants. By the last 14th century, Count Johann I ruled over a small and poor county under the Habsburgs. In the Battle of Näfels in 1388, the count commanded a wing of the Austrian army that was supposed to cross the Kerenzerberg Pass. However, when he saw the threatened destruction of the main Austrian army, he fled back over the pass. The cost of the war, as well as other expenses forced Johann I to sell the castle and village to Leopold of Austria.
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.
