Slovenian School Museum Free entrance to the Slovenian School Museum (for permanent and occasional exhibitions); 10% off publications. The Slovenian School Museum in Ljubljana, founded in 1898, is the oldest specialised museum in Slovenia focusing on a specific sphere of man's activities. Unlike the Provincial Museum in Ljubljana (1821) and the municipal museums in Celje (1882) and Ptuj (1895), the Slovenian School Museum was not limited to the territories of the then administrative units; the museum can thus be regarded the first Pan-Slovenian museum. Exhibitions of teaching aids were organised before an institution of this kind came into existence, promoting the idea of a school museum and increasing teachers’ interest for studying the history of schools and pedagogy in the territory populated by the Slovenian nation.
