A very well done piece on the construction of the Cathedral of St. Sava in Belgrade, Serbia. The temple (it’s actually not a cathedral in the technical sense of the word as it’s not the seat of a bishop) is said to be the largest Orthodox church in the world.
One of the most interesting parts of the video is when it shows how the 4,000 ton central dome was raised — in 40 days! The temple is near completion with some interior work left to be done.
For those interested, a listing of the largest church buildings in the world.
