Sverresborg was built by king Sverre Sigurdsson (ca. 1150-1202) in the mid 1180s, 250 meters northeast of Bergenhus fortress. King Sverre Sigurdsson also had a Sverresborg built in Trondheim. It is thought that the fortress had an outer wall of stone and inner buildings of wood. A saga mentions that 600 men and 40 noble women lived in the fortress ca. 1207.Sverresborg was the site of several battles during the Civil war era in Norway. The castle fell to the baglers and was destroyed, but was rebuilt by Håkon Jarl. The baglers destroyed it a second time and it has been rebuilt several times.The site was reinforced by King Håkon Håkonsson after the great fire of 1248. The medieval fort remained until mid-16th century. Directly underneath Sverresborg lies the residence of the master of the ramparts, the oldest of which go back to the 18th century. The master of the ramparts was in charge of the maintenance and upkeep of the fortifications and buildings. Much of the present day fortifications are from the 17th century. In August 1665, the fortress participated in the Battle of Vågen. The last known expansions took place during the Napoleonic wars.
In the 1830s a park was laid out in the area and in 1911 a petty officers school was established for Bergen Brigade. During World War II the German occupants established two anti aircraft batteries in the fortress. After the war, Sverresborg used as the execution site in connection with treason settlement. Seven German and one Norwegian war criminals were executed in Sverresborg in 1946.
The fortress has not fulfilled an operative capacity since World War II, but is still used by the military of Norway for office facilities. The facilities include a garage and an outbuilding of more recent date. The area is today under the command of the commandant of Bergenhus and is a military area, but open to the public.
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.
