Godesburg castle was built in the early 13th century on the Godesberg, a hill of volcanic origin, it was largely destroyed following a siege in 1583 at the start of the Cologne War.
The site has a controversial history. First mentioned in documents from the early 8th century, there was supposedly an old cult site and its name derived from the old Germanic Wotansberg, Woudensberg, or Gotansberg.
The fortress foundation stones were laid by a vicar upon the order of Dietrich I, the Archbishop of Cologne. After Dietrich's death in 1224, his successors finished the fortress; it featured in chronicles of the 13th through 15th centuries as both a symbolic and physical embodiment of the power of the archbishop of Cologne in his many struggles for regional authority with the patricians of the imperial city of Cologne. By the late 14th century, the fortress had become the repository of the Elector's valuables and archives, and by the mid-16th century, was popularly considered the lieblingssitz, or the favorite seat (home), of the Electors.
The fortification had been originally constructed in the medieval style and in the reign of Siegfried II of Westwald (1275–1295) successfully resisted a five-week siege by Count William of Cleves. Successive archbishops continued to improve the fortifications with stronger walls and expanded moats, adding levels to the central Bergfried, which was cylindrical, not square like many medieval donjons, expanded the inner works to include a small residence, dungeons, and chapel, fortified the walls, added a curtain wall, and improved the roads. By the 1580s, it was an elaborate stone fortress, and it had been enhanced partially in the style made popular by Italian military architects.
In 1959, the ruin was rebuilt according to plans by Gottfried Böhm, to house a hotel and restaurant. Today, the restaurant is still in operation, but the hotel tract has been divided into apartments.
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.
