could never be moved and has since remained well-preserved, but closed to the public. The Nationale Konst-Gallery opened in
Huis ten Bosch in 1800 but moved after the government changeover in 1805 to make room for the new inhabitant of Huis ten Bosch,
Rutger Jan Schimmelpenninck. The collection was moved to the former
Prince William V Gallery, now part of the museum known as the
Gevangenpoort. In 1808 it moved again according to the wishes of
Lodewijk Napoleon to the
former city hall of Amsterdam. Though Roos lived and worked in (
Huis met de Hoofden) Amsterdam, the position of inspector in Amsterdam was given to
Cornelis Apostool and Roos went back to his dealership. Roos became a member of the Royal Institute, predecessor to the
Royal Netherlands Academy of Arts and Sciences, in 1808. ==Art collection==
