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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
