The exhibition on the 500th anniversary of the birth of Protestant priest Primoz Trubar (1508-1586) is celebrating the man who wrote and published the first Slovenian books, thus laying the foundations for Slovenian written language and cultural development in general.

The exhibition was on show until 31 December 2008, but has been prolonged until 30 April 2009. It features over 150 items from his day and age, including the only remaining copy of his 1564 "Cerkovna ordninga", the first legal text in Slovenian.
