It is a historical fortress complex that integrates the Palace, the Nossa Senhora da Luz Fortress, and a contemporary art district. The site maintains a formal link to the Presidency of the Portuguese Republic, often serving as a venue for official state events. Visitors access restored state rooms that reflect the interior aesthetic of the late 19th-century royal court.
