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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
