In 1906, the chaplain of the cathedral, Alexander Newtgen, donated his collection to the city of Cologne and stored it at the Schneidergen Museum in the Romanesque St. Helens Church, which is considered one of the most important medieval art museums in Europe. The museum preserves church art from the early Middle Ages to the Baroque period from the perspective of using space and art to play a role together. The international first-class art exhibits span a 1,000-year history, such as ivory carving, gold products, wood and stone sculptures, Bronze and silver art treasures, church furniture, painted glass, manuscripts, service clothes and fabrics from the late classical period to the present. It is because of these medieval church artworks that the Cologne Schneutgen Museum has become one of the world's most important medieval collections.
