The Baptistery of San Giovanni ad Fontes is a religious edifice in Lomello. An example of Romanesque-Lombard architecture, it is annexed to the basilica of Santa Maria Maggiore, another early Middle Ages structure.
The baptistery has a typical cross plan, but in the interior the central part forms an octagon, over which is a dome of the same shape. The interior is wholly plastered, and can be accessed from two portals. The baptistery has, on the east-west axis, an overall length of 16 m.
The main element is the baptismal font, dating to the 7th-8th centuries.
The baptistery has an elevation of 13 m and is entirely built of brickworks, parts of which date to the 5th-6th centuries. The dome is a later addition (c. 10th century), and was built using less precious materials.
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.
