Vozdovac is a municipality of Belgrade. Its emblem includes a black boar's head looking quite frumious at the golden arrow stuck in its forehead. The lower image is of a blue rose.
A boar's head in heraldry often represents a feast, and by extension, hospitality. But in this case, the boar's head pierced with an arrow is a symbol of the Triballi, an ancient Thracian tribe from the plains of the Serbian Danube near the junction of the Angrus and Brongus (the south and west Morava).
Medieval Byzantine historians referred to the Serbs as the Triballians and during the First Serbian Uprising against the Ottoman Empire, the boar's head symbol was used by the Serb leader Karadojordje Petrovic, who had the nickname 'Black George'.
The red, white and blue in the flag are from the Pan-Slavic tricolour of the Serbian Flag.
The blue rose usually represents either Mary Magdalene or the Virgin Mary in Christian art. The five thorns around the rose represent the five wounds of Christ when He was crucified. The central red rose often represents martrydom or it could be associated with Rosicrucianism.
