Monastery of San Pedro de las Dueñas was built in the late 10th century and beginning of the 11th century. It is one of the most representative churches of Mudejar Romanesque in its Pre-classical period, began in stone and finished in brick (1087 and 1110) and Basilical ground plan.
Over the presbytery of the chancel stands a brick tower, it is square with progressively decreasing sections.There is an interesting collection of capitals. The most remarkable of them is the one known as 'de las siete monjas' (the seven nuns capital) and the chancel shows an interesting Christ by Gregorio Fernández.
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.
