Torretrencada is a Talayotic settlement (1000-700 BCE) that was occupied until the Roman conquest in 123 BCE. Several of its monuments can still be seen. They include the talayot a seriest of artificial burial caves dug out of the rocky ground and burial chambers carved in the rock, probably dating from the high medieval period. The taula is one of the most beautiful on the island, with a reinforcement pillar at the back, but all that is left of the surrounding wall is a section underneath the modern dry-stone wall. The site dates back to the post-Talayotic period (650-123 BCE) and was used by the community for performing rituals.
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.
