The Raya or frontier between the kingdoms of Castile and Aragón was fortified with a system of castles and walled-cities that were useful during the several conflicts that took place in the late Middle Ages. The Serón de Nágima castle defended the communication road between the axis of the Jalón river valley, which flows into the Ebro, and Duero valley. Its uniqueness stems from the fact that it is one of the few fortifications in the area where rammed earth is the only building system used. In this paper, the castle building fundaments are exposed mainly focusing on the techniques and building processes developed from the interpretation of the legible constructive signs in its walls.
The late medieval strategy for delimitating and defending the frontier between Castile and Aragón was in its systematic fortification. Ancient castles and Muslim fortifications were repaired and new buildings for defense were erected. The aim of the author's Doctoral Thesis, which gathers from the present paper, is to know the construction techniques of a selection of these castles, so as to interpret the building activity of that historical moment and analyze the systematization of these construction techniques within the historical, geographical and architectural context.The research method consists of a fieldwork in which a series of castles are documented and surveyed; they are previously selected after analyzing the bibliographical works of the medieval Soria's castellology.
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.
