The Church of Old Saint Peter's in Strasbourg is first mentioned in 1130. On 22 May 1398 the Chapter of the Abbey of Honau, which had been in Rhinau since 1290, moved to Old St Peter's because of flooding in Rhinau. The Chapter stayed there until 1529, conducting its services in the choir, while the parish occupied the nave. When the Catholic rite was restored in 1683, the Chapter returned to the Church and stayed there until 1790, when it was wound up.
On 20 February 1529, when Strasbourg openly joined the Reformation and suspended the practice of the mass, the Church became Lutheran. Martin Bucer and the other Strasbourg reformers had campaigned for several years to have Protestant services in all of Strasbourg's churches, but in 1525 the city council had voted to retain the mass in several churches, including Old St Peter's. In 1535, in the context of the Reform, a Latin school, or 'Middle school' was opened at Old Saint Peters.
In 1683, two years after the annexation of Strasbourg by France, Louis XIV ordered that part of the Church be returned to the Catholics and that a wall be constructed inside the church by the rood screen, to restrict the Protestant services to the Nave. It was not until 2012 that a door was opened in this dividing wall.
In the 19th century, the Catholic part of the Church was extended. The extension was designed by the architect Conrath and opened in 1867.
The Catholic Church contains relics of Brigit of Kildare as well as a number of important works of art classified as Monuments historiques such as the 'Cycle of the Passion of Christ', a series of ten Gothic paintings by Heinrich Lutzelmann (1485), the 'Scenes from the Life of St Peter' an (incomplete) series of four wooden early Renaissance or late Gothic reliefs made around 1500 and a series of four 1504 paintings depicting 'Scenes of the Life of Christ after the Resurrection'.
The Lutheran part of the church, presently owned and used by a congregation within the Protestant Church of Augsburg Confession of Alsace and Lorraine, also features some notable works of art, among which the wooden Renaissance relief 'Holy Family' (1520s) by Hans Wydyz, classified as a Monument historique.
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.
