スモレンスク公国
The Principality of Smolensk was founded in 1054. Due to its central position in Kievan Rus', the city developed rapidly. By the end of the 12th century, the princedom was one of the strongest in Eastern Europe, so that Smolensk princes frequently controlled the Kievan throne. Numerous churches were built in the city at that time, including the church of Sts. Peter and Paul (1146, reconstructed to its presumed original appearance after World War II) and the church of St. John the Baptist (1180, also partly rebuilt). The most remarkable church in the city is called Svirskaya (1197, still standing); it was admired by contemporaries as the most beautiful structure east of Kiev.
