The first documents of Zalatambor Castle date back to 1024. This fort became known since the 13th century as the castle of Zalatambor, coinciding with the first fortifications made in the main rock.
In addition to the successive extensions and reforms of Zalatambor, the defense of the city was reinforced with the construction of a new castle, Belmecher, in 1276, and a tower as a defensive watchtower that, following the mountainous ridge, guarded the path of Castile. The three fortifications were joined by a wall forming the Estella castle enclosure, totally independent from the city.
Zalatambor Castle was a royal residence during the 13th, 14th and 15th centuries, with numerous rooms prepared for this purpose. However, since the mid-15th century the state of the castle, the result of the crisis caused by the civil war between Agramonteses and Beaumonteses, forced the monarchs to lodge during their stay in the noblest houses of the city.
In 1512 , the Beaumontesa-Castilian coalition conquered the castle, which, along with the rest of the kingdom, passed into Castilian hands. However, it continued in use until 1572, when the new defensive plan against France led to the construction of the citadel of Pamplona and the abandonment of the medieval Navarrese castles.
Its partial destruction was carried out by blowing up the main defensive elements. However, the current state of the castle is mainly due to its use as a quarry, documented in numerous lawsuits since its blasting.
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.
