Located on the Danube River, the Old Town of Regensburg is an exceptional example of a central-European medieval trading centre, which illustrates an interchange of cultural and architectural influences. The property encompasses the city centre on the south side of the river, two long islands in the Danube, the so-called Wöhrde (from the old German word waird, meaning island or peninsula), and the area of the former charity hospital St Katharina in Stadtamhof, a district incorporated into the city of Regensburg only in 1924. A navigable canal, part of the European waterway of the Rhine-Main-Danube canal, forms the northern boundary of Stadtamhof.
A notable number of buildings of outstanding quality testify to its political, religious, and economic significance from the 9th century. The historic fabric reflects some two millennia of structural continuity and includes ancient Roman, Romanesque, and Gothic buildings. Regensburg's 11th to 13th century architecture still defines the character of the town marked by tall buildings, dark and narrow lanes, and strong fortifications. The buildings include medieval Patrician houses and towers, a large number of churches and monastic ensembles as well as the 12th century Stone Bridge.
The town is also remarkable as a meeting place of Imperial Assemblies and as the seat of the Perpetual Imperial Diet general assemblies until the 19th century. Numerous buildings testify to its history as one of the centres of the Holy Roman Empire, like the Patrician towers, large Romanesque and Gothic church buildings and monasteries – St Emmeram, Alte Kapelle, Niedermünster and St Jakob - as well as the cathedral St Peter and the late Gothic town hall.
The medieval centre of the city is a UNESCO World Heritage Site and a testimony of the city's status as cultural centre of southern Germany in the middle ages. Regensburg is among the top sights and travel attractions 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.
