On the northwestern flank of Christiansborg, aside from the cupola of the Royal Chapel (1826), the Thorvaldsens Museum is of Greek-Roman inspiration (1839-1848) and houses neoclassical works of art from the great Danish sculptor, Bertel Thorvaldsen (1770-1844). Thorvaldsen's career was mainly based in Rome but in 1838, he returned triumphant to Denmark and was made an honorary citizen of Copenhagen.
