The collections at the National Gallery of Denmark comprise three main collections: The Royal Collection of Painting and Sculpture, The Royal Collection of Graphic Art, and The Royal Collection of Plaster Casts. As the names suggest, these collections have their roots in the art collections of Danish monarchs; they are believed to date back to King Christian II and the mid-16th century. The Collection of Sculpture and Painting comprises approximately 10,500 paintings and sculptures, while the Collection of Graphic Art houses more than 245,000 works of art on paper. In addition to this, approximately 2,500 plaster casts are housed at the Royal Cast Collection. New works are added to the collections every year. Generous donations and acquisitions have shaped the profile of the collections in recent years, but the starting point remains the collections built by Danish monarchs.
