Saint Sophia Cathedral in Kyiv was completed in 1037 during the reign of Yaroslav the Wise. The ruler was buried in the church in 1054 in a six-ton marble sarcophagus that still survives.
Although the cathedrals exterior was remodeled into the Ukrainian Baroque style in the 17th century, its original Byzantine interior was preserved. It was the first Ukrainian monument to be inscribed onto the World Heritage List.
