cemeteries. Discovery and investigations of the graves After the fall of Communism in Yugoslavia, hundreds of unmarked mass graves were found in Slovenia. The Tezno mass graves were found during the construction of a motorway near Maribor in 1999, when workers came upon an anti-tank trench that stretched several kilometres. It was estimated that the part intended for the motorway contained around 600 corpses. Subsequent excavations revealed that there were 1,179 corpses in a 70 meter long part of the trench. On average there were 17 corpses found buried along each meter of it. The trench was covered with gravel and lime was found on top of the human remains. Most exhumed corpses indicated that the victims' arms were tied with wire. Individual skulls had visible gunshot wounds. In 1999, the Slovenian police initially estimated there were between 7,000 and 10,000 victims buried in the trenches. A new exhumation began in 2007. The Commission on Concealed Mass Graves in Slovenia reported that their analysis and conducted probing of what is now a forested area in Tezno found human remains at a length of 940 meters. Based on mathematical calculations and comparisons with the excavations in 1999, it is estimated to contain the remains of around 15,000 victims. The collected documentation and preserved items of victims indicate that they were largely members of the HOS. The historian Mitja Ferenc notes that among the victims were also some members of the Montenegrin National Army, who were incorporated into the HOS that year, and probably a few members of Muslim militias, the German Army, and the Hungarian and Albanian battalions of the HOS (Hungarista legion and Skanderbeg legion). Jože Dežman, head of the Commission on Concealed Mass Graves, referred to Tezno as the largest mass grave in Europe following the end of World War II. The part of the trench in Tezno in Maribor is officially designated the Tezno Woods 1 Mass Grave. The Tezno Woods 2–6 Mass Graves () lie west of the settlement of Dogoše, between the Zlatoličje hydroelectric plant canal and Maribor, and are part of a former antitank trench. Commemoration After the discovery of the graves, memorials were erected commemorating the deaths of the victims. In September 2007, the Slovene government started plans to make the mass grave site in Tezno a memorial park and a cemetery. Croatian president Ivo Josipović visited the site in June 2010 and laid
