It is not known with any certainty when Dill castle was built, but it is assumed that this happened in the 11th century, and that it might have been built on the ruins of an earlier Roman or Celtic complex.
At the complex's highest point, in the north, is the Oberburg (“upper castle”). Not much of the four-floor residential tower, whose sides measured 18 × 12 m, is left other than three outside walls; the east wall is missing. On the north wall's outer side is a garderobe. Parts of the barrel-vaulted cellar may still be visited. West of the upper castle, remnants of the girding wall have been unearthed. They exhibit a herringbone pattern in their construction.
On the area of the Niederburg (“lower castle” or “bailey”) to the east stand an Evangelical church, built on the spot where the castle chapel once stood, a wellhouse, which has been expanded into a holiday home, and a modern house.
Of the Vorburg (“forward castle” or perhaps “outer bailey”) to the west and south, only remnants of the foundations and outer wall can still be found. Part of the area is used as a garden.
The castle is in private ownership and normally cannot be visited. However, once or twice a year, there are guided tours. The times are published.
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.
