Here's a wonderful 45-minute documentary on the world's most northernmost monastery, the Trifonov Pechengsky Monastery, located around Murmansk on the Arctic Sea. It's in Russian, but with good subtitling. The film features unique footage of inner life of the monastery.
Life at the monastery is difficult to say the least. The monks often seem more playful, casual than you might expect, but when you listen to their words you see the intensity of their faith.
UPDATE: Friend who watched part of this video describes it as a real slice of "Unreal Reality"!
