Acerno Cathedral is a Roman Catholic cathedral, dedicated to Saint Donatus of Arezzo. From the 11th century it was the seat of the Bishop of Acerno. The bishopric was united to the Archbishopric of Salerno in 1818 to form the Archdiocese of Salerno-Acerno, renamed in 1986 the Archdiocese of Salerno-Campagna-Acerno, in which Acerno Cathedral is a co-cathedral.
Construction of the present building began in 1575 on the ruins of an earlier church which was declared the cathedral of the diocese of Acerno in 444 by Pope Leo I. As a consequence of many earthquakes, in particular that of 1980 and the fire that followed it, the structure has undergone numerous changes. As a result of a reconstruction project in 1989 the building has been completely restored and reopened for worship.
The interior, on a Latin cross floorplan, consists of a central nave and two side-aisles, a transept, an apse and a sacristy, as well as the usual service areas. Because of the recent destruction no reliefs or decorative works are now to be seen, except for some 18th-century frescoes attributed to Leonardo Pallante and the high altar.
As for the building's exterior, the very plain west front has a principal central doorway between two smaller ones, above which are two windows to either side of a small central rose window beneath a simple Classical pediment containing an oculus. The bell tower has four storeys and terminates in an onion dome with a metal shell.
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.
