The Church of St. Florian was commissioned by the citizens of Ljubljana in memory of the great fire which devastated the Stari trg and Gornji trg squares in 1660. Built after 1672, the church burnt down in 1774. Since then it has undergone several reconstructions. It was given its present appearance by the architect Jože Plečnik, who reconstructed it between 1933 and 1934.
Plečnik had the former door recess filled with the statue of St. John Nepomuk carved by Francesco Robba in 1727 for the chapel by the bridge over the Sava river in the suburb of Črnuče, landscaped the church's surrounding area, and built the nearby walking path to Ljubljana Castle. The large fresco of Our Lady of Mercy above the church door was painted by Janez Potočnik at the end of the 18th century. The niches above the fresco are adorned with statues of Charles the Great and St. Charles Borromeo. A supposedly original portrait sculpture of a citizen of the Roman Emona is built into the wall above the terrace. The church's interior still boasts Baroque paintings of saints, altars and other furnishings.
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.
