In 1825, the Queen engaged the archaeologist Marquess Luigi Biondi (1776–1839), whose excavation work uncovered Tusculum. In 1839 and 1840, the architect and archaeologist Luigi Canina (1795–1856) was engaged by the royal family and excavated the Theatre area of Tusculum. The ancient works of art excavated were sent to the Duke of Savoy's Castle of Agliè in Piedmont.
