The Schnütgen Museum in Cologne is devoted to Christian religious art, mainly medieval, but some parts of the collection, such as its textiles and prints, extend from antiquity to the modern period. In 1906, the collection of Alexander Schnütgen was donated to the city, and the collection has continued to expand, so that until the opening of a new building in 2010, only about 10% of its 13,000 items could be displayed.
