The Basilica of Sts. Vitalis, Valeris, Gervase and Protase is commonly named Basilica di San Vitale. It was built in 400 with funds provided by Vestina, a wealthy dowager, and was consecrated by Pope Innocent I in 401/402. The dedication to St. Vitalis and his family (Saint Valeria, his wife, and Sts. Gervasius and Protasius, their sons) is dated to 412.
San Vitale was restored several times, the most important being the rebuilding by Pope Sixtus IV before the Jubilee of 1475, and then in 1598, 1938 and 1960. The church is currently located several metres under the level of the street (via Nazionale), that it faces.
The portico is the most ancient part of the church, possibly dating back to the 5th century. It was altered at the end of the 16th century. The inscription on the portico, with the arms of Pope Sixtus IV, dates from this time. Pope Pius IX built the staircase to the 5th century portico in 1859.
The church has a single nave, with walls frescoed with scenes of martyrdom, among which a Martyrdom of St Ignatius of Antioch, in which a ruined Colosseum is depicted. The apsis, original of the 5th century, is decorated with a fresco by Andrea Commodi, The Ascent to Calvary.
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.
