The era of High Baroque represents the second zenith of art in the Slovenian lands after the Gothic period. Supported by benevolent church and aristocratic patrons, art production flourished in a stable political environment and favourable economic situation. As the diocesan and administrative centre of the province, Ljubljana became the undisputable hub of art. As the new Baroque church replaced the old Gothic cathedral and the monastery basilica of the Knights of the Teutonic Order yielded its place to Domenico Rossi's architecture based on the centralized design, Ljubljana in a relatively short time changed its look from a Central European hamlet to a town of the Mediterranean character. Commercial advantages stimulated a rapid formation of a trilingual culture, where Slovenian, German and Italian languages were used indiscriminately.
The invited Italian artists started a golden age in all art fields and exerted influence on the development of local art production. The central place went to the Venetian sculptor Francesco Robba who produced both sacred and secular works; outstanding among them is his fountain of the Carniolan rivers as the identification symbol of the city of Ljubljana. Painting is represented in the Grand Hall by the monumental canvases of the immigrant Valentin Metzinger, the oldest in the group of four Ljubljana Baroque painters. The expressed religious emotion, dynamic composition, imaginary and celestial landscapes, and colour harmony in the works by Metzinger remained the standard of quality and a source of inspiration deep into the 19th century. His altar paintings often found place in the churches where fresco decoration was executed by Franc Jelovšek, who, in turn, built his style on the examples of Giulio Quaglio and contemporary Austrian fresco painting. Jelovšek made only a very few works in oil of which his Holy Family is the best and is the artist’s contribution to the Baroque veneration of the Mother of God.
In the Grand Hall, single representative works by several other Baroque painters active in Central Europe are also on display: Pieter Mulier, Giambettino Cignaroli and Martin van Meytens the Younger, while Franz Karl Remb grew up in Radovljica and made his career in Vienna and Graz.
