St. Peter’s Cathedral
Around 739 the site of the Cathedral was chosen in the area of the Porta Praetoria north gate of the old Roman fort. The Cathedral was later rebuilt and expanded during the 11th century. It was rebuilt in the Gothic style commencing 1273, with continual work until 1538. More work continued over the centuries with the towers and their spires built 1859-1869. A magnificent location indeed, the architecture that you will see here is a site-seekers dream.
Altes Rathus and Clock Tower
From the Steinerne Bridge walking towards the Old Town, then you will see the Old Town Hall. Built during the 15th century, however the tower was built 200 years earlier. The first Holy Roaman Empire parliament sat here from 1663 to 1806.
Valhalla
The hall of fame "Walhalla" is housed in a neo-classical building above the Danube River. Even if you don't visit the inside, the building itself and the view over the Danube valley are worth going there. The entrance to the hall of fame is 4 €, the view over the Danube river and the place itself are for free! Even if you do not visit the inside of this location, the outside alone is something that you surely don’t want to miss.
Niedermunster
Niedermünster, located east of the cathedral, was not a monastery but a convent of unmarried noble ladies who lived in a community without taking vows as nuns. After the convent was closed down in the early 19th century, the convent buildings became the seat of the Bishops of Regensburg. The church is the central catholic parish church for the old town. The church is almost 1000 years old.
