San Giovanni a Porta Latina (Italian: 'Saint John Before the Latin Gate') is a Basilica church near the Aurelian Wall. According to Tertullian, in year 92, St John the Evangelist survived martyrdom at Rome under the Emperor Domitian by being immersed in a vat of boiling oil, from which he emerged unharmed. He was later exiled to island of Patmos. This event was traditionally said to have occurred at the Latin Gate (located on the southern portion of the Roman wall). The nearby chapel of San Giovanni in Oleo is said to be on this very spot. The event was referred to in the Roman Martyrology, which was begun in the seventh century, when already there was a celebration of the event.
The tradition for the building of the Basilica of St. John at the Latin Gate places its construction during the pontificate of Pope Gelasius I (492-496). This is consistent with the oldest of the roof tiles, which have the imprint of a taxation stamp for the Ostrogoth King and ruler of Italy Theodoric the Great (reigned 493-526). One of these ancient roof tiles is now used in the Basilica as a lectern.
In the 8th century, the Basilica was restored by Pope Adrian I, and later the bell-tower and portico were added, and at the end of the 12th century the Basilica was reconsecrated by Pope Celestine III. In the 16th and 17th centuries, a Baroque ceiling and other Baroque features were added to the interior. In the years 1940-1941, the Baroque features were removed and the Basilica was returned to a more primitive simplicity. This last renovation was carried out by the Rosminian Fathers, who, in 1938, were given care of the Basilica and the nearby building, where they opened the Collegio Missionario Antonio Rosmini which houses their International House of Studies.
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.
