The Serbian military cemetery in Thessaloniki, built in the area of Zejtinlik (former Turkish market) where the Main Military Hospital for the Serbian Army has been located since 1916. and which included a cemetery for deceased fighters, was designed with the idea of burying in a common cemetery for all the fallen warriors on the Thessaloniki front. Preparations for the endeavor to build a joint memorial ossuary began in 1926. with the organization of a competition for the mausoleum of fallen Serbian warriors and the collection of remains in a wide area where fighting was taking place on the Thessaloniki front. Milan Zloković also took part in the competition for the memorial ossuary, whose conceptual design was based on a combination of a fortification structure in a massive rustic pedestal and a neo-Byzantine shape of the upper zone finished with a dome and imbued with several suggestive elements from expressionist vocabulary. The transition between the lower and upper zones is solved by inserting a gable frame on all sides of the central symmetrical body. The inventiveness of Zloković’s solution was reflected in the combination and superposition of several stylistically different parts into one coherent whole.
