Montfort Castle was built by the Counts of Veldenz around the year 1200. The first known dweller at the castle was Eberhard von Lautern (1182-1240). Lautern family owned the castle until 1432. In 1456 the army of archbishop of Mainz and Elector Palatine Frederick I destroyed the castle in local feud.
Despite some repairs Montfort stayed ruined several centuries until the remains where repaired in the 20th century. Today the castle can be visited free. There is also a small museum.
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.
