A spring in the Białowieża Forest, located 3 km from Hajnówka on the Hajnówka-Białowieża route, considered miraculous by the Orthodox Church.
Krynoczka (a spring, a source), was formerly known as the Miednoje forest, from the name of a stream flowing nearby. It is a place of annual pilgrimage for the feast of the Holy Trinity. Nearby stands a wooden church, built in 1846, dedicated to the Holy Brothers Maccabees, belonging to the parish of the Dormition of the Most Holy Mother of God in Dubiny. By the well (currently located under a shelter), a small wooden chapel was built in 1848 from donations from local believers.
According to legends cultivated by the Orthodox, the cult of the holy spring in the Miednoje forest was known in the 13th century and was associated with the existence of a small monastery there, founded by monks fleeing the Tatar invasion. Another legend tells of a miraculous revelation of the icon of the Mother of God on a nearby tree.
The cult of the spring, documented in the 19th century, was only local, and the Holy Liturgies in the local chapel were held only on the day of the commemoration of the Brothers Maccabees and on the feast of the Exaltation of the Lord's Cross. Since 1894, the third day of liturgical celebrations has been the second day of the Holy Trinity. Krynoczka was also known to monks from the Monastery of the Holy Spirit in Vilnius, who, on pilgrimage to the monastery in Wirów and to the monastery in Leśna, stopped there to pray with the local residents.
Pilgrims visiting Krynoczka traditionally wipe the sick place with a handkerchief moistened in its water, and then leave it on the fence behind the well, thus symbolically getting rid of the disease. The place is included in the travel plan in the tab - Recommended trips, weekend in Podlasie.
