Puertas de Tierra is a bastion-monument built around remnants of the old defensive wall at the entrance to the city of Cadiz. Built by academic architect Torcuato Cayón in the 18th century, the cover is carved in marble and was intended more as a religious altarpiece than as a military fortification.
It is one of the most significant monuments of the city and on its walls flies the purple flag of its canton.
The adjustment to the new architecture of the city, opening the two new arcs, is performed by the architect Antonio Sánchez Esteve.
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.
