Yugoslav-era

During the time period of Yugoslavia, Necropolis at Sremska Mitrovica was a highly visited memorial site and hosted large-scale annual commemorative ceremonies. These were often attended by high ranking dignitaries and government officials, such as Yugoslav president Josip Broz Tito himself attending ceremonies in March of 1965. During this era, the complex underwent several phases of additions and changes to its layout, much of these occurring with the direct involvement and participation of its architect Bodgan Bogdanović. In 1975, the first major renovation effort egan at the complex, which involved not only cleaning and repairing the site's memorial elements, but also adding some new elements. Included within the efforts was a vast tree planting endeavor and the addition of a collection of small memorial works representing various Yugoslav republics. In addition, work began on a modest museum facility for the park (presumably designed by Bogdanović. given its eccentric appearance). However, the museum was not fully completed during the phase and it was left partially realized. Then, just a few years later, another phase of changes were made to the park via Bogdanović's specifications between 1978 and 1981. These changes included a reconfiguration of the space, with the inclusion of a low hedge maze at the center of the complex (in an effort to slow down the visitor to remind them that they are in a sacred space), as well as additional burial mounds to symbolize the new autonomous zones of Yugoslavia, a concrete wreath wall within the processional courtyard and a circular stone paved stage by the park's south entrance. Also during this time, the unfinished museum complex was demolished and a much more simple museum exhibition structure was built, taking the form of a traditional Srem house designed in the local vernacular style (with plasters walls and a wooden porch).
