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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
