St. Katharinen

Osnabrück Cathedral was founded in 785, fifteen years after Charlemagne founded the bishopric. After its destruction by the Normans in 890, it was restored. The damage caused by fire in 1254 required considerable repairs, the vault of the passage was rebuilt and the pillars of the passage were reinforced. The rectangular choir begun later was completed in 1270, and the new high altar was consecrated in 1277. However, the ambulatory and the Lady Chapel were not added until 150 years later, between 1434 and 1444. Between 1454 and 1482, Bishop Konrad III had the entire building renovated. Until around 1500, the cathedral had two Western Romanesque towers of the same size. From 1509 to 1544, the south tower was replaced by the larger Gothic tower of today, which was given a high pyramidal pointed roof. Alexander Behnes, who was responsible for the preservation of the building from 1882 to 1910, made several modifications and additions.

St. John's Church is a former collegiate church dating from the 13th century and one of the oldest Gothic hall churches in Germany. When the church was consecrated on 18 August 1292, the construction work was not yet complete. The work continued until the beginning of the 14th century. It is a three-aisled hall church with an east transept and an enclosed rectangular choir. Between the choir and the southern arm of the transept is a sacristy. To the north, the cloister is connected to the transverse chapel used as a prayer room.

Built between 1963-1965 as St Bonifatius Church by architects Michael Kleffner and Christa Kleffner-Dirxen. Renovated 2005-2006 by agn Niederberghaus & Partner. Repurposed 2015 as Media House of the Diocese of Münster, preserving its architectural features.
