Wallraf–Richartz Museum

The Wallraf, Richartz Museum, officially known as the Wallraf-Richartz-Museum & Fondation Corboud, is an art museum in Cologne, Germany, and the oldest museum in the city. Founded in 1824, it holds one of the world's most extensive collections of medieval panel paintings, particularly works of the Cologne School, alongside significant holdings spanning from the medieval period to the early twentieth century. Located in the Altstadt-Nord district near Cologne Cathedral, the museum occupies a building designed by Oswald Mathias Ungers that opened in 2001. It is one of Cologne's three major museums and ranks among the great classical painting galleries of Germany.

The museum traces its origins to the testament of Ferdinand Franz Wallraf (1748-1824), a Cologne canon and the last rector of the old University of Cologne. In his will of 18 May 1818, he bequeathed his extensive collection, largely assembled from secularized church property, to the city under the condition that it remain for the benefit of art and science. The collection first opened to the public on 8 July 1827 in rooms of the former archiepiscopal quarters, the "Kölner Hof" on Trankgasse 7, under the name Wallrafianum. Matthias Joseph de Noël served as the first curator until 1842, followed by Johann Anton Ramboux, who advocated for a purpose-built museum. The decisive impetus came from Cologne merchant Johann Heinrich Richartz (1796-1861), who in 1851 pledged 100,000 talers for a new building, eventually increasing his total donation to 277,000 talers. The foundation stone was laid on 4 October 1855 in the presence of King Friedrich Wilhelm IV of Prussia, and the English Neo-Gothic building designed by Josef Felten with Julius Carl Raschdorff and Friedrich August Stüler opened on 1 July 1861. The museum underwent reorganization in 1921, when it was divided into an "Old Gallery" and a "Gallery of Modern Times," a structure that proved unsuccessful and was reversed by 1928 under director Ernst Buchner. Otto H. Förster became director in 1933 and from 1941 sold 630 works he deemed "worthless" or "low-value," using the proceeds to acquire works of questionable provenance from occupied eastern territories. The 1861 building was completely destroyed in an air raid on the night of 28-29 June 1943. A replacement building designed by Rudolf Schwarz and Josef Bernard opened on 27 May 1957 at the same site, but its limited capacity soon prompted plans for relocation. The decisive moment came with the acquisition of the Peter Ludwig collection in 1968, leading to a competition won by Busmann + Haberer. The resulting complex, shared with Museum Ludwig and the Cologne Philharmonic, opened on 6 September 1986. The museum finally moved to its current location near Cologne City Hall in 2001, into a building designed by Oswald Mathias Ungers. That same year, Swiss collector Gérard Corboud placed his collection of over 170 impressionist and post-impressionist works on permanent loan, prompting the addition of "Fondation Corboud" to the museum's name. Marcus Dekiert has served as director since 2013. The museum is scheduled to close for civil engineering works from August 2026 to late 2028.

The Wallraf, Richartz Museum presents a comprehensive survey of European art across approximately 3,500 square meters, covering the thirteenth century to the early twentieth century. Its medieval holdings constitute the world's most extensive collection of medieval panel painting, a remarkable survival attributable to the absence of major fires or iconoclasm in Cologne until the Second World War. The museum's graphic collection numbers more than 75,000 catalogue raisonné, with roots traceable to the mid-sixteenth century through the former Jesuit museum in Cologne. The collection is organized chronologically across several departments: Gothic painting, with particular strength in the Cologne School; Renaissance and early Netherlandish art; Baroque and Rococo painting with emphasis on Dutch masters; nineteenth-century art from Romanticism through Symbolism; and the impressionist and post-impressionist works of the Fondation Corboud, which form the most extensive collection of French and international Impressionism in Germany. The nineteenth-century galleries were completely reinstalled in 2008 with updated lighting, color schemes, and didactic presentation.

Among the museum's signature medieval works is Stefan Lochner's Madonna of the Rose Bower, painted circa 1450, depicting the Virgin and Child in a blooming rose arbor with Lochner's characteristic child angels. The same artist's Last Judgment and Annunciation are also held. Another outstanding Gothic panel is the Arrest of Jesus by the Master of the Karlsruhe Passion, the only surviving panel from that painter's influential Passion cycle not in the Staatliche Kunsthalle Karlsruhe. The museum also holds the Jabach Altarpiece panel by Albrecht Dürer and an altarpiece of 1515 from Great Saint Martin Church by Jacob van Utrecht, one of his few known works.

The Baroque collection features Peter Paul Rubens's Juno and Argus (circa 1610) and The Miraculous Draught of Fishes, a self-portrait by Rembrandt, and works by Jacob Jordaens, Frans Snyders, Anthony van Dyck, Frans Hals, Gerrit van Honthorst, Pieter de Hooch, François Boucher, Jean-Honoré Fragonard, and Giambattista Pittoni. The Fondation Corboud holdings include works by Claude Monet, Camille Pissarro, Alfred Sisley, Gustave Caillebotte, Berthe Morisot, Édouard Manet, Pierre-Auguste Renoir, Paul Cézanne, Paul Gauguin, Vincent van Gogh, and Henri Matisse. Other notable works include Caspar David Friedrich, Wilhelm Leibl, Max Liebermann, Arnold Böcklin, James Ensor, and Edvard Munch in the nineteenth-century galleries, and sculptures by Jean-Antoine Houdon and Auguste Rodin.

In 2008, the museum announced that On the Banks of the Seine by Port Villez, acquired in 1954 and attributed to Monet, was a forgery discovered through X-ray and infrared examination revealing a colorless substance applied to simulate age. The museum retained the work and still holds five authentic Monet paintings.

The museum's current building was designed by Oswald Mathias Ungers and opened in 2001. It stands near Cologne City Hall on a site of significant archaeological importance: the former location of the Roman temple to Mars in the ancient city of Colonia Claudia Ara Agrippinensium. The building forms part of a cultural complex in the city center. Its immediate predecessor, the Busmann-Haberer building of 1986, had housed the museum in shared quarters with Museum Ludwig and the Cologne Philharmonic. The 1957 Schwarz-Bernard building on the original site, which had replaced the destroyed 1861 structure, now accommodates the Museum für Angewandte Kunst Köln. The Ungers building provides purpose-designed gallery spaces for the chronological presentation of the collection, though the Fondation Corboud collection has remained largely in storage due to space constraints, with plans for expansion under consideration since 2001.

The Wallraf, Richartz Museum is located in Cologne's Altstadt-Nord district, in the Ungersbau complex near the Cologne City Hall and in proximity to the Cologne Cathedral. It is owned by the city of Cologne and operates as a public municipal museum. The museum maintains a website at wallraf.museum. Visitors should note that the museum will be closed for civil engineering works from August 2026 to late 2028. As one of Cologne's three major museums, it functions alongside the Museum Ludwig, which assumed the twentieth-century collection after the 1976 division, and serves as a principal institution for the study and display of European painting from the medieval period through Impressionism.
