At the time of global commemorations of World War I centenaries, the Slovenian National Committee for the 100th Aniversary of World War I initiated in 2015 an attempt at including World War I heritage and the Walk of Peace in world and European cultural heritage lists. The proposal was supported by numerous municipalities along the former Isonzo Front and on 16 December 2015 also by the Government of the Republic of Slovenia which appointed the Walk of Peace Foundation as the coordinator of the work group whose head was Dr. Petra Svoljšak. The work group, which also included representatives of the Ministry of Culture, Ministry of Defence, and the Institute for the Protection of Cultural Heritage, prepared materials for entering World War I heritage and the Walk of Peace on the territory of the Republic of Slovenia in the Unesco Tentative List. On 29 January 2016, the committee for world heritage agreed to enter the said heritage and the Walk of Peace in the Unesco Tentative List, which is the required intermediate step in the procedure.
In the following years, a comprehensive technical part of the Tentative File was prepared. Like other candidates for tentative nominations for 20th century war heritage, the Slovenian work group too is now waiting for the decision and guidelines from the international expert group on the remembrance sites related to the recent conflicts.
