The Royal Palace of Venice is a complex of buildings located in the central St. Mark's Square of Venice, Italy, which served as the residence for Napoleonic viceroys, the kings of Lombardy-Venetia, Austrian viceroys, and finally, the monarchs of unified Italy. The use and successive modifications of the Royal Palace began in 1807 and ended in 1919 when King Victor Emmanuel III ceded the building to the Italian State. Currently, the complex is divided between the National Library of Venice, the Archaeological Museum, and the Correr Museum.
