After the Romans left Günzburg in the fifth century, the Alamanni tribe settled there. In around 700 the nearby castle of Ricinis was mentioned by the Cartographer of Ravenna as one of the five most important castles of Alemannia. In 1065 first documentary evidence appears of the town itself as Gunceburch. In 1301 the town became part of the Habsburg house and was developed into the centre of the Margraviate of Burgau; for a time (1803–1805) it was even the capital of all Further Austria.
After the construction of a castle and church in the south-western corner of the upper town (1577/80), Günzburg became the residence of Archduke Ferdinand II`s son Karl from 1609 until 1618. Margrave Karl was able to bring craft and trade to new heights, but later all his efforts were ruined by the Thirty Year War (1618–1648) in the course of which the number of Günzburg`s citizens went down from about 2,400 to some 800. The castle went up in flames (1703) and the citizens suffered badly under the occupation.
Today the the margraves' castle is the main tourist attraction. It is the only Habsburg castle built in Germany.
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.
