The Church of St. John the Theologian was built at the expense of parishioners in 1814 on the site of a wooden one.
The church in the village of Kupan existed back in the XVI century, it is mentioned in documents from 1563.
The wooden church in honor of John the Theologian was in Kupan at the end of the XVIII century, until 1782 it had a wooden church of the Great Martyr Barbara.
Instead of a wooden church, a two-story stone church was built in 1814 with the zeal of the parishioners. On the upper floor there is a throne in honor of the Apostle and Evangelist John the Theologian, on the lower floor there is the Great Martyr Barbara.
In Soviet times, the church was closed, and in 1996 it was returned to the faithful.
