One of the largest Eastern Orthodox cathedrals in the world, built between 1882 and 1912 to honour the soldiers — Russian, Bulgarian, Finnish and Romanian — who fell in the war that freed Bulgaria from Ottoman rule. Neo-Byzantine, designed by Alexander Pomerantsev. Italian marble, Brazilian onyx, Bavarian stained glass. The central dome is gold-plated and visible from most of Sofia's higher streets. The crypt below holds the country's main collection of medieval Orthodox icons.
