Schloss Baldern was first mentioned in historical documents in the 11th century. In the mid-12th century, it was owned by a noble family known as the Edelfreien von Baldern. In 1280, the castle came into the possession of Count Ludwig V. von Oettingen. In the 15th century, it was pledged by his descendants and later redeemed in 1507. The current baroque appearance as the residence of the Counts of Oettingen-Baldern was established between 1718 and 1737. The construction was overseen by Franz de Gabrieli, and after his death, by his brother Gabriel de Gabrieli.
After the extinction of the noble family Oettingen-Baldern in 1798, the estate passed to the House of Oettingen-Wallerstein. Major renovations took place in the 19th century, including the landscaping of the hilltop into a landscaped garden. The tower was erected in 1887 under the direction of August von Beyer. As early as 1896, Schloss Baldern was opened to the public.
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.
