The Temple of St. Sava in Belgrade, Serbia, is the 2nd largest orthodox church in Europe, and one of the largest in the world. It is also one of the most beautiful and iconic symbols of Belgrade, and lies on the Vracar plateau.
It is built on the same spot in which the remains of St. Sava were burnt by the Ottoman Turks in 1594. The building of this temple had started in 1935, but was halted in the early stages for many decades (partially due to the wars), and not until the late 1980s did it begin to take its more completed form. The golden crosses on the top, had been added at the turn of the century. The entire enterior (painting and decorations, chandeliers) were only added in the recent few years - the walls were just a blank concrete before then; and it was largely financed by the donation from the Russian government. The underground crypt is especially beautiful and ornate.
I have taken a short video of both exterior during the day and night, as well as the enterior, including the aforementioned crypt.
