Which cathedral in Germany is the world’s largest surviving Romanesque church?

Speyer Cathedral in Germany is the world’s largest surviving Romanesque church.

The cathedral was founded in 1030 by Emperor Conrad II and was substantially rebuilt and enlarged during the 11th century. Its massive scale reflects the ambitions of the Salian emperors, who intended Speyer to serve as an important imperial and dynastic centre.

The building’s Romanesque character can be seen in its rounded arches, thick masonry, large crypt, and orderly monumental forms. Its crypt is among the largest Romanesque crypts in Europe and contains the burials of several German emperors and kings.

Speyer Cathedral suffered damage over the centuries, especially during wars, but major restoration campaigns preserved its essential medieval structure. UNESCO added it to the World Heritage List in 1981.
