At the proposal of the Polo Museale del Friuli Venezia Giulia, the Civici Musei (City Museums) of Udine have joined "Museums without Borders", an initiative which aims to promote the “improvement of the knowledge and dissemination of the culture and history of the European peoples” in accordance with the principles set out in the Lisbon Treaty.

This international agreement applies to Slovenia, Croatia and Italy and entitles visitors from these member states (in this case, Slovenia and Croatia) to obtain a 50% discount on ticket prices at participating museums, provided that these visitors are in possession of a valid ticket (free or purchased) issued by one of the other participating museums in the preceding 20 days. This reduction applies only when the original ticket is either a single or family ticket.

The museums taking part in the initiative are as follows: EKOMUZEJ BATANA, ETNOGRAFSKI MUZEJ ISTRE, POMORSKI I POVIJESNII MUZEJ HRVATSKOG PRIMORJA RIJEKA, POVIJESNI I POMORSKI MUZEJ ISTRE, HRVATSKI MUZEJ TURIZMA, MUZEJ ANTIČKOG STAKLA, CIVICI MUSEI DI UDINE, CIVICI MUSEI DI TRIESTE, FONDAZIONE PALAZZO CORONINI CRONBERG O.N.L.U.S., MUSEO STORICO E IL PARCO DEL CASTELLO DI MIRAMARE, POLO MUSEALE DEL FRIULI VENEZIA GIULIA, ERPAC-MUSEI PROVINCIALI DI GORIZIA, GORIŠKI MUZEJ, PILONOVA GALERIJA AJDOVŠČINA, KOBARIŠKI MUZEJ, POMORSKI MUZEJ-MUSEO DEL MARE “SERGEJ MAŠERA” PIRAN-PIRANO, POKRAJINSKI MUZEJ KOPER-MUSEO REGIONALE DI CAPODISTRIA, SLOVENSKA KINOTEKA Z MUZEJEM SLOVENSKIH FILMSKIH IGRALCEV V DIVAČI, TOLMINSKI MUZEJ, PARK VOJAŠKE ZGODOVINE PIVKA, OBALNE GALERIJE PIRAN, and NOTRANJKI MUZEJ POSTOJNA-ZAVOD ZNANJE POSTOJNA.
