renovations had to be paid from the construction fund, and embellishments from gifts. Since 1822, some innovations of the interior were done. The abundance of stalls was reduced to a functional density. Unfortunately, some most valuable medieval stalls were destroyed that way. In 1839/40, a new main altar in Gothic Revival style was installed, and 1847 to 1849 a new organ. In the 1860s, the cathedral got its first coloured stained glass windows after the Reformation. Restoration By the 1880s the citizens of Bremen decided that the cathedral should be restored to its medieval glory. The idea was predominantly promoted by Franz Schütte. Money was raised for the restoration of the building and work began in 1888. Reconstruction continued off and on until 1901 when the church reopened. The restoration was done close to the status before and old pictures, but with a few additions in Romanesque Revival and Gothic Revival style. The whole concept was developed by Max Salzmann. The towers were raised to their present height and completed in 1892. The interior of the church was restored in the Gothic style making it difficult to see the changes in style that occurred over time. The northern tower that had collapsed in the 17th century was newly erected from its foundations, but using recent structures of the northern tower and old depictions of the cathedral as an example. Of the northern tower it is unknown even to the authorities concerned today, if the lower four storeys were kept or pulled down and rebuilt almost identically. The upper storeys were redesigned a bit. The mosaics in the two central arcs of the façade were new. The gallery above the entrances was restored a bit more solid, and the rose window a bit more decorated than they had been. On the northern façade the gables of the transept and above the Brautportal ("Bride Door") were new, and the Bride Door itself was redecorated, now it has Gothic Revival design. The addition of the crossing tower was a challenge of engineering, the four columns of the crossing had to be displaced by more stable pillars, but the medieval vaults were kept. Inside, the walls were repainted in a Neo-Byzantine style. World War II and new repairs The church was struck by a fire bomb during an Allied air raid in 1943 and damaged repeatedly until 1945 when a high explosive bomb caused
