Wilhelmsburg was built from 1842 to 1849 as the Citadel's reduit. The Citadel comprised work XII of the Wilhelmsburg and works XIII to XVIII of Fort Wilhelm and was the largest of the town-wall fortifications. In contrast to all the other works; the ›Wilhelmsburg‹ had no ramparts and consisted only of four re-inforced bunkers in the three towers. Over the decades, different regiments and units were stationed here.
After the Second World War, the Wilhelmsburg was officially used as a refugee camp, although several citizens of Ulm, whose homes had been bombed or requisitioned, also took shelter here. At any one time, a total of almost 3,000 people lived in the ›Wilhelmsburg‹, which had its own shop, post office and school.
In 1956, the newly formed German army moved in and up until 1970, soldiers were still stationed in the bunkers of the Wilhelmsburg.
Since then, the more than 570 rooms have been empty, apart from a few that have been rented out to companies.
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.
