Joseph I of Portugal
The first new remodelling to the Palace occurred in the 18th century, with the installation of an organ in the chapel. In 1716 King John V began minor renovations. Later, in 1762 under Queen Maria I of Portugal, the construction began of the main tower fronting the Duchess's Garden (or "Forest Garden") and of a new wing, formally designated as the "Quartos Novos" ("New Quarters"). This included the "Sala de Jantar" ("Dining Hall"), which along with the other works, was finally completed under her successor, King Joseph I of Portugal in 1770.
