St. Peter's Parish Church is one of the oldest churches in Ljubljana. The original church at the site was presumably built near the city walls already at the turn of the 9th century on the order of Paulinus II, the Patriarch of Aquilea. It was the seat of the Primitive Parish of Ljubljana. The church was encircled by a cemetery that was the main town cemetery until 1779, when it was abandoned.
The current building was erected in a Baroque style between 1730 and 1733 upon the plans of the architect Carlo Martinuzzi, who based them upon the Church of San Giorgio Maggiore in Venice. The model of the church was made by Giovanni Fusconi, who also gave some technical advice. The church was built by the master builder Gregor Maček, Jr. Interior division of the church has been preserved from the period.
After the Ljubljana earthquake of 1895, the church was renovated by the architect Raimund Jeblinger in a neo-baroque style. This renovation was strongly criticised for its supposed low quality, and was followed by another, done between 1938 and 1940. The façade was completely remodeled by the architect Ivan Vurnik, while his wife Helena Vurnik contributed new interior decorations and mosaics. The church's ceiling frescoes are the work of baroque painter Fran Jelovšek; altar paintings are by Valentin Metzinger.
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.
