The Alcázar of Seville is a royal palace, built for the Christian king Peter of Castile. It was built by Castilian Christians on the site of an Abbadid Muslim residential fortress destroyed after the Christian conquest of Seville. The palace, a pre-eminent example of Mudéjar architecture in the Iberian Peninsula, is renowned as one of the most beautiful. The upper levels of the Alcázar are still used by the royal family as their official residence in Seville, and are administered by the Patrimonio Nacional. It was registered in 1987 by UNESCO as a World Heritage Site.
The original nucleus of the Alcázar was constructed in the 10th century as the palace of the Muslim governor. Built and rebuilt from the early Middle Ages right up to our times, it consists of a group of palatial buildings and extensive gardens. The Alcázar embraces a rare compendium of cultures where areas of the original Almohad palace - such as the 'Patio del Yeso' or the 'Jardines del Crucero' - coexist with the Palacio de Pedro I representing Spanish Mudejar art, together with other constructions displaying every cultural style from the Renaissance to the Neoclassical.
Some gardens have Renaissance statues. After damage by the 1755 Lisbon earthquake, that façade of the Palacio Gótico overlooking the Patio del Crucero was completely renovated in Baroque style.
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.
