San Sebastián is a fortress located in Cádiz, at the end of La Caleta beach on a small island separated from the main city.
According to the classical tradition of the location of the fortress, there was a Temple of Kronos, a Titan of the Greek gods, the father of Zeus, Poseidon, Hades, Hestia, Demeter and Hera. In 1457, a chapel on the island was raised by a Venetian boat crew recovering from the plague. In 1706, a castle was constructed, which resulted in a fortified enclosure of an irregular plane. It defended the northern flank of the city from attack. At the base of the lighthouse was a watchtower from the Muslim period. The lighthouse has an iron structure designed by Rafael de la Cerda in 1908 and is the second electric powered lighthouse in Spain. The tower rises to 41 meters above the sea.
In 1811 the Maltese navy arrived with the famous POW/rebel Junta of Buenos Aires, Juan Bautista Azopardo. He was housed in the fortress until 1815, when they suspected a leak and transferred him to the military prison in Ceuta.
In 1860, a levee was built to serve as a link between the island and the city. On June 25 of 1985, Castillo de San Sebastian was declared a cultural landmark.
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.
