Schloss Heiligenberg is a Renaissance-style castle owned by the Fürstenberg family. It is located on a plateau 730 metres above sea level, with views down onto the Bodensee and the Alps. It was first built in the Middle Ages - in 1250 count Berthold of Heiligenberg built a burgh on the site, which was bought in 1277 by count Hugo of Werdenberg. Under the counts of Werdenberg-Heiligenberg, the castle expanded during the late Middle Ages.
Through countess Anna of Werdenberg's marriage to count Friedrich zu Fürstenberg in 1516, the burgh passed to the house of Fürstenberg in 1535 - it is still owned by that family today. Shortly before his death in 1559, Friedrich decided to remodel the castle in the Renaissance style. The building as it is seen today dates to count Joachim (1538–1598), who from 1560 to 1575 rebuilt the late medieval burgh into a 'schloss', with a Renaissance-style courtyard and an extended ballroom wing to the south.
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.
