St Sophia’s Cathedral, one of eight UNESCO World Heritage sites in Ukraine, is one of the few surviving buildings from the Kyivan Rus' era and one of the most important Eastern Orthodox shrines in all of Europe.
Built in the 11th century, it preserves not only the high art of the time period but also remnants of everyday medieval life. Namely, 7,500 inscriptions - including notes, names, prayers, and drawings - left by ordinary inhabitants of Kyiv.
