Schloss Waldenfels is a castle complex in the Mühlviertel region of Upper Austria, located 500 meters south of the town of Reichenthal. According to tradition, the first castle was built around 1290 by brothers Heinrich and Eberhard von Wallsee. However, Waldenfels was first mentioned in records in 1380 as a fief of Duke Albert III. In 1390, the duke purchased the estate and pawned it to the Starhemberg family in 1396. Between 1449 and 1461, the pawned estate passed to the Lower Austrian Plankensteiner family, as Hans von Plankenstein transferred the castle to Reinprecht von Polheim in 1461. In 1474, Waldenfels was besieged by Jaroslav Lev of Rosental, the Chief Steward of the Kingdom of Bohemia, and the outlawed Freistadt patrician Zinispan.
In 1584, the last pawnholder, Joachim Stangel, bought the castle from Emperor Rudolf II, and his family retained ownership until 1636. In that year, Konstantin Grundemann von Falkenberg purchased the estate, and it has remained in the family ever since. After World War II, the castle housed around 700 Soviet soldiers, and the following 12 years were spent repairing the damage from the occupation. The current owner is Dominik Grundemann-Falkenberg.
The castle is situated on a gentle slope and consists of an extensive, irregular group of buildings incorporating medieval, Renaissance, and Baroque elements. Its current appearance dates to the early 17th century. A courtyard with a 1702 well is surrounded by two-story wings with arcaded galleries from the 16th century. The courtyard is partly enclosed by a massive, square tower with a Baroque onion dome and a crenellated wall. The residential buildings are two-story structures. Above the stone portal, which includes a small door and a large gate, is the coat of arms of the Counts Grundemann.
The medieval main castle was integrated into the existing structure. The southwestern terrace, known as the 'Tournament Court' from the 17th century, is now a garden enclosed by an arched wall. One wing contains an artificial grotto with stalactites and a female figure.
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.
