It was built on a site where two or possibly three churches stood earlier between 1646 and 1660 (the bell towers following around 1720) under the management of Francesco Olivieri and Francesco Rosina, and its exterior was redesigned in 1858 according to plans by Franz Kurz zum Thurn und Goldenstein [sl].

New ceiling frescoes were painted in 1935–1936 in the Baroque trompe-l'œil manner by the Slovene otherwise impressionist painter Matej Sternen.

[5][6][2] The front facade of the church was built in the Baroque style in 1703–1706 and completely redesigned in 1858 according to the plans of the Austrian painter Franz Kurz zum Thurn und Goldenstein [sl].

[3] Its red colour replaced the earlier classical white, a Goldenstein's fresco of four Church Fathers was added above the entrance (in 1882 it was replaced by a fresco by Janez Wolf [sl]), and a statue of Our Lady of Loretto, i.e. Madonna with Child, was added at the top of the facade.

It features the richest monastic library in Slovenia,[9] which contains over 70,000 books, including many incunables and medieval manuscripts.
