The Castle of Biar stands on a hillock overlooking the town of Biar. During the Muslim rule had already news but few of the fortress, which began to be relevant to the time of James I of Aragon, remain as border castle under the Treaty of Almizra. The building lost its role during the early modern period and, although rarely used, after was used as a cemetery.
The castle was built in stone with masonry and rammed earth, which was used for the tower of homage. The building consists of two parts. On the one hand, a semicircular enclosure with four towers at the corners thereof, and on the other, a space with four cubic structures and the tower of homage. These towers and other structures are the basic defenses of the castle, and its position high on a rocky hill, the proliferation of small openings in its walls and battlements auction.
The tower of homage is the highlight of the architectural complex. Dating from the 12th century, the tower, situated on one side, was built with mortar mixture of sand and lime and reaches a height of 19 metres. Its plan is square shaped and has three floors, acquiring such an enormous importance. On the lower floor is used the called barrel vault and the other levels, second and third, use the Almohad ribbed vault which, together with those of the neighboring Castle of Villena, are among the oldest in Spain and throughout the Maghreb, as well as the only used in a military building in the Iberian Peninsula.
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.
