Catherine's Church (Tserkva Ekateryny) at the edge of Val Hill is the baroque jewel of Chernihiv — a church built at the end of the 17th century in the distinctive Ukrainian baroque style that flourished under Cossack patronage. The exterior is covered in green and white ornament: elaborate white stucco frames around the windows, cornices of stylised scrollwork, and the characteristic massing of Ukrainian baroque with its vertical emphasis and onion-domed cupolas.
The church stands on the slope below Val Hill with a view over the lower town. Its scale is modest but its detailing is extravagant — the facade combines Renaissance pilasters with Ukrainian folk ornament in a way that is unlike any Western European baroque. The interior retains its original iconostasis. The church is used for regular Orthodox services; check opening hours before planning a visit specifically to see the interior.
