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 Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
