Collegiate Church of Saint Gertrude
The collegiate church of Saint Gertrude, built between 992 and 1046, is one of the oldest and largest surviving Romanesque churches. Five successive churches, built between the 7th and 10th centuries, preceded the Romanesque church. The present church was consecrated in the presence of Emperor Henry III (1046-1056). Heavily modified over the centuries, the church took on its present pseudo-Romanesque appearance thanks to a restoration carried out by Simon Brigode after the Second World War.
