It is the seat of the Roman Catholic Diocese of Osnabrück. The origins of the first church and diocese can be traced all the way back to the great Charlemagne who founded the first church at this spot in the year 785. Wars and fires have taken their toll on the old church and so it saw a lot of changes over the centuries. The current church built in the late Romanesque style dates back to the 12th century and has a Baroque interior as a result of the changes in styles of time.

This place is a must for every visitor. Overlooking the square is the beautiful Lutheran St Mary's Church built in the gothic style, dating back to the 14th century.

Finished in 1512, the Town Hall designed in the late gothic style was the location for the negotiations that would end the The Thirty Years War (1618 - 1648) that had a lasting impact on central Europe. The main hall contains 42 portraits of the envoys representing the nations at the peace congress, as well as the rulers of the time. There is a replica of the treaty as well as many prominent relics of the imperial times located here.

Passing through the pedestrian zone flanked by gorgeous 15th century half-timbered and sandstone houses, we approach the portal, a war memorial dedicated to the soldier that fought at the battle of Waterloo.

Have a view towards the Felix-Nussbaum- House with its unusual modern architecture, and next to it is the Museum of Culture.

The garden of the palace is where you will also find the City Palace. This grand building used to be the residence of the protestant bishop and is now used as an administration building for the city's university. Built in the Baroque style, it serves as the residence for many bishops and princes. This palace was the birthplace of King George I. of England, a german prince on the english throne who would continue to carry on the tradition of german monarchs ruling the British Empire right up to Queen Victoria.
