The current edifice of Basilica of Sant'Abbondio rises over a pre-existing 5th century Palaeo-Christian church entitled to Sts. Peter and Paul, built by order of St. Amantius of Como, third bishop of the city. Erected c. 1 km outside the city's walls, it was intended to house several relics of the two saints which Amantius had brought from Rome.
The basilica acted as bishop's seat until 1007. Six years later bishop Alberic moved the seat within the walls. The basilica was then entrusted to the Benedictines who, between 1050 and 1095, rebuilt it in Romanesque style. The new edifice was dedicated to Amantius' successor, Abundius. The structures of the Palaeo-Christian church, discovered in 1863 during a restoration, are still marked by black and pale marble stones in the pavement.
The new basilica had a nave and four aisles. It was consecrated by pope Urban II on June 3, 1095.
The church has two notable bell towers rising at the end of the external aisles, in the middle of the nave. The sober façade, once preceded by a portico, has seven windows and a portal. Notable is the external decoration of the choir's windows. There are also Romanesque bas-reliefs and, in the apse, a notable cycle of mid-14th-century frescoes. Under the high altar are the Abundius' relics.
The medieval monastery annexed to the church, recently restored, will act as the seat of the local faculty of Jurisprudence.
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.
