In Kalemegdan there is a tomb of national heroes that was constructed in 1948. Granite panels mark two gravesites of Djura Djakovic (1886-1929), Ivan Milutinovic (1901-1944) and Ivo Lola Ribar (1916-1943). They were brought in from the construction site of St. Sava's Temple and in 1957 Mosa Pijade (1890-1957) was also buried here.
