Nativity of Christ Cathedral, Riga, Latvia

Nativity of Christ Cathedral was turned into a Lutheran church during the World War I and German occupation of Riga but it was restored as Orthodox Cathedral in 1921. The communist authorities closed the cathedral and converted it into a planetarium in the 1960's. The Nativity of Christ Cathedral was renovated and restored as a Orthodox cathedral after Latvia gained independence from the Soviet Union in 1991 but the locals still name it the 'Planetarijs'.
