The Saints Konstantin and Elena Church is one of the oldest Christian churches in Plovdiv.
In the year 304, in the place where the church is found today, the martyrs Severiyan and Memnos were beheaded, along with 38 of their followers. The church was founded about 30 years later to commemorate their sacrifice for the Christian faith.
The church was destroyed many times during Ottoman rule, and the current one dates back to 1832. Located in the heart of Old Plovdiv, it is the most visited religious site in the city.
