A 12th-century church on the northern edge of the city — one of the very few Kyivan Rus buildings to survive almost intact above ground. The exterior was given a Baroque overlay in the 18th century, but the cross-domed plan inside is original, and so are some of the 12th-century frescoes.
The frescoes are the reason to go. The standout work is by Mikhail Vrubel: a young, unknown artist when commissioned to restore the church in the 1880s, he ended up painting four new icons whose intensity prefigures his later masterpieces.
