The Palace of Queluz is a Portuguese 18th-century palace located at Queluz in the Lisbon District. One of the last great Rococo buildings to be designed in Europe, the palace was conceived as a summer retreat for Dom Pedro of Braganza, later to become husband and then king consort to his own niece, Queen Maria I. It served as a discreet place of incarceration for Queen Maria as her descent into madness continued in the years following Dom Pedro's death in 1786. Following the destruction by fire of the Ajuda Palace in 1794, Queluz Palace became the official residence of the Portuguese prince regent, John VI, and his family and remained so until the Royal Family fled to the Portuguese colony of Brazil in 1807 following the French invasion of Portugal.
Work on the palace began in 1747 under the architect Mateus Vicente de Oliveira. Despite being far smaller, the palace is often referred to as the Portuguese Versailles. From 1826, the palace slowly fell from favour with the Portuguese sovereigns. In 1908, it became the property of the state. Following a serious fire in 1934, which gutted the interior, the palace was extensively restored, and today is open to the public as a major tourist attraction.
One wing of the palace, the Pavilion of Dona Maria, built between 1785 and 1792 by the architect Manuel Caetano de Sousa, is now a guest house allocated to foreign heads of state visiting Portugal.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
