The Church of St. John the Baptist in Asenovgrad is situated on the West of the city on the edge of a cliff. Locals common name "St. John's Church". Its creation is attributed to the 13-14 centuries, according to some versions – 11th century..the definition of age structure predominantly based on its architectural features. It was built as the chapel, however, due to relatively large size (length - 8 meters width - 5.5, about 5 in height) is recognized by the Church. A single-nave structure with a three-sided apse and a narthex. The building is constructed of cut stone, alternating with strips of brick. The facade is decorated with blind arches and fake niches. The Church of St. John on top in the North wall are six slits similar to the slits, if necessary they served as the defensive element for the building and transformed it into a kind of fortress.

The Church has five blind arches on the North and South walls and the West wall has three normal arches. The apse has a triangular shape and has three small Windows. Wall thickness of about one meter. 800 years ago "Saint Yan" was a fortified Church and together with the fortress of St. Michael the Archangel defended Stanimaka (the ancient name of Asenovgrad) from the North.
