St. Cyril's Church
Kyiv, Ukraine · built 1139
The St. Cyril's Monastery (Kyrylivskyi monastyr) is a medieval monastery in Kyiv, the capital of Ukraine. The monastery contains the famous St. Cyril's Church, an important specimen of Kievan Rus' architecture of the 12th century, and combining elements of the 17th and 19th centuries. However, being largely Ukrainian Baroque on the outside, the church retains its original Kievan Rus' interior.
