In 1178, Ferdinand II of León donated the Ponferrada city to the Templar order for protecting the pilgrims on the Way of St. James who passed through El Bierzo in their road to Santiago de Compostela. Their castle was originally a hill-fort and later a Roman citadel. Templar knights took possession of the fortress and reinforced and extended it to use it as an inhabitable palace.
However, the Templars were only able to enjoy the use of their fortress for about twenty years before the order was disbanded and its properties confiscated in 1311. Several noble houses fought over the assets until Alfonso XI allotted them to the Count of Lemos in 1340. Finally the Catholic Monarchs incorporated Ponferrada and its castle into the Crown in 1486. Most of the walls were removed and used in local construction projects.
The building has an irregular square plan and the outstanding features are, above all, the entrance which involves crossing the moat on a drawbridge and, further on, two large towers with crenellations joined by an arch. Its twelve original towers reproduced the shapes of the constellations.
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.
