Towering high above the old town of Kronach on Rosenberg hill is Rosenberg Fortress, the former palace of the Prince Bishops of Bamberg and later a regional stronghold. It was officially mentioned first time in 1249.
The early building on the Rosenberg became the castle of the prince-bishop and was, thus, immured and enlarged in the years that followed. Another section of walls, along with the Arsenal Gate in the South, the Old Arsenal and the former construction of the present-day Commander's Building, were developed under the reign of the prince-bishop Philipp von Henneberg (1475-1487).
After the experiences of the Margrave War in 1553, the prince-bishop Veit II von Würtzburg ordered his master builder Daniel Engelhardt to complete the ward as a four-winged fortification. Soon extensions and new constructions of the Old and New Arsenal followed. In the 1570s bastions were developed.
The worst time for the town and the fortress happened to be the Thirty-Year War, when the Swedish tried to capture Kronach several times from 1632 to 1634. Due to the steadfastness of the inhabitants and to the defence readiness of the fortress, whose outer ring still consisted of soil and wood bastions at that time, the plan had failed. The Swedish left Kronach.
After the Thirty-Year War the fortress Rosenberg was armed with lithic bastions in their contemporary shape. In 1699, under the reign of prince-bishop Lothar Franz von Schönborn (1693-1729), the fortification was finished.
In 1867, Rosenberg lost its fort property and in 1888 the town of Kronach acquired it for 32,000 Deutsche Mark, and still own it today.
During the First World War, the fortress served as a prison camp for officers. One of the inmates was the later French president Charles de Gaulle. After World War II, several refugees found shelter in the fortress. Some years later, flats were set up in the Old Arsenal and The Commander's Building. Some of them still existed in the 1970s.
Today, the fortress is one of the largest remaining fortifications in Germany, covering 23.6 hectares. The complex of walls, moats, buildings and gates that emerged over the centuries is still completely surrounded by the fortress pentagon with its five mighty bastions.

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.
