Which Byzantine cathedral in Kyiv was begun under Yaroslav the Wise in the eleventh century?

Saint Sophia Cathedral is the Byzantine-influenced cathedral in Kyiv begun under Yaroslav the Wise in the eleventh century.

The cathedral was built during the Christianization and political consolidation of Kyivan Rus. Its design drew heavily on Constantinopolitan traditions, while its scale and decoration expressed the ambitions of the Rusian state. The interior preserves important medieval mosaics and frescoes.

Construction is generally associated with the reign of Grand Prince Yaroslav the Wise, although the precise starting date and workforce remain subjects of scholarly discussion. The cathedral’s name refers to Holy Wisdom, not to a woman named Sophia.

Saint Sophia Cathedral is often compared with Hagia Sophia in Constantinople because both use the dedication to Divine Wisdom. They are different buildings, however, and Kyiv’s cathedral developed its own distinctive multi-domed silhouette.
