Villa Rebar - Zagreb, Croatia

Villa Rebar is on the outskirts of Zagreb and was built in 1932. It was home to a Croatian fascist dictator, Ante Pavelic, known for genocide against Jews, Serbians and Romani. While he lived there, the dictator added a tunnel system leading to military bunkers nearby, which were also used as escape tunnels. When the war was over, Pavelic fled his home, which eventually became a mountain resort. However, in 1979 a fire wiped out the resort and it now stands in graffiti-strewn ruins.
