The Church of the Assumption (Uspenie Bogorodichno) is the main Orthodox church in Koprivshtitsa, dating to the 1817 rebuilding on an older foundation. Like many Bulgarian churches built under Ottoman rule, it is set below street level — the result of restrictions that limited the height of Christian buildings. You step down into it.
Inside, the church is dark and richly decorated, with an elaborate carved wooden iconostasis and icon paintings in the Bulgarian National Revival style. The courtyard around it is shaded by old trees and serves as a quiet retreat from the lanes outside. The church is still in active use; if a service is in progress, wait at the entrance and enter quietly when it concludes.
