The National Gallery, Slovenia's foremost museum of historical art, holds the country's largest collection of fine art from the High Middle Ages to the 20th century. It also houses a permanent exhibition of works by Zoran Mušič (1909–2005), one of Europe's leading modernist painters, and various temporary exhibitions.
The National Gallery's permanent collection, divided into sections according to historical periods, is comprised of nearly 600 works by Slovenian and European artists. Among other things, it includes medieval sacred art, works of art by the Baroque artists Gregorio Lazzarini in Giulio Quaglio, Biedermeier portraits by Jožef Tominc, neoclassical paintings by Franc Kavčič, works by the Realists Janez Šubic and Jurij Šubic, paintings by the popular Slovenian painter Ivana Kobilca, and the famous masterpieces of Slovenian Impressionism created by Ivan Grohar, Rihard Jakopič, and Matija Jama.
The gallery also keeps one of the largest pieces of Baroque art in Ljubljana, the Fountain of Three Carniolan Rivers by Francesco Robba, whose original site in front of the Town Hall is now occupied by its replica.
Apart from the above, the National Gallery houses a room called Gal's Room, where children's and family events are held on a regular basis, an extensive library, a gallery shop with a reading corner, and a café.
