The magnificent dome of Saint Sava Temple in Belgrade showcases breathtaking Byzantine-style mosaics covering over 15,000 square meters with shimmering gold leaf backgrounds. The central apse depicts the Dormition of the Mother of God surrounded by apostles and saints, while the dome's intricate religious scenes and decorative patterns represent one of the largest Orthodox church interiors in the world. Built on the site where the Ottomans burned the relics of Saint Sava in 1594, this temple took over 80 years to construct and its interior mosaics were only completed in recent decades by Russian and Greek artists.
