Narodna galerija (National Gallery of Slovenia) is the main art museum in Slovenia containing the largest visual arts collection from the late medieval period to including the twentieth century.
The National Gallery Society was founded in 1918, although the endeavors to establish a home of Slovenian art (an "acropolis" as it was named on the founding) had already been initiated towards the end of the 19th century. Thus from the first dreams of the initiators, and with the high cultural awareness of all Slovenians, the National Gallery developed into one of the most eminent cultural and artistic institutions. Already on 22 June 1933, the Gallery had arranged the ceremonial opening of the expanded permanent collection of Slovenian art. From all parts of the homeland and from abroad there arrived congratulatory telegrams and greetings-cards to mark the great event. The Gallery had achieved professional success and was beginning to enjoy a great reputation among the Slovene public.
