A couple walks in front of the war memorial monument "Battle of Sutjeska" in Tjentiste, Bosnia and Herzegovina, June 16, 2019. Examples of Yugoslav brutalism include the huge memorials commemorating the struggle against fascism, often placed in dramatic rural settings. Many of those pieces of art remain in disrepair, however, the Tjentiste memorial, commemorating the killing of 7,000 people by the Nazis was renovated last year.

During her long life, Terez Majsztrovics has never left her small village, hidden at the end of an asphalt track amid the rolling hills of the Hungarian lowlands. But the world came to her, in wave after wave. Born in 1934, she saw German, Russian and Hungarian troops march across the area in World War Two, then, once the Yugoslav border was established, she spent a few decades "three hills away" from a frontier fortified by Communists. During the harshest days of Stalinism, Hungary built a fence along the border, complete with a minefield. It was an "Iron Curtain", built against a perceived threat from the South. When relations eventually thawed in the 1950s, that fence came down. But, sixty years later, another one went up, and the border was sealed off again.
