The first mention of the former manor house of the Lords of Velen dates back to 1240. It was not until 1426 that the property with the central wing built at that time was given the title of 'castle'.
In the following centuries, the most famous architects of the region gave the moated castle their signature: Master builder Ambrosius von Oelde, Johann Conrad Schlaun , Ignaz Franz von Landsberg-Velen, painter August Reinking, the Düsseldorf garden artist Maximilian Friedrich. All of these master architects designed the harmonious ensemble of the moated castle, from the courtyard front to the south wing and the castle park, until the 19th century.
Although all this art was largely destroyed by a fire in 1931, it was rebuilt with some internal changes. During and after the Second World War, the building served various public purposes. From 1988 to 2018, Schloss Velen was operated as a sports hotel. Today, the building houses a well-equipped seminar and conference centre.
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.
