The decision had taken years to weigh and would, within a generation, transform Bulgaria from a Turkic-speaking pagan steppe federation into a Christian Slavic kingdom whose script would eventually be used by half of Europe. To mark his choice, Boris ordered an enormous basilica built at his capital - Pliska - on the precise spot where his ancestors had worshiped older gods. By 875 the new church was finished. It was 102.5 meters long and 30 meters wide, one of the largest Christian buildings of its century anywhere in Europe. Its ruins still stand on the rolling Bulgarian plain, foundations the height of a man's chest, walking-arc apse facing east toward the rising sun.
