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:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
