The Sanctuary of Holy Water in Wasilków is part of the Archdiocese of Białystok. It is renowned not only for its challenging history but also for the intriguing legend connected to it. Importantly for many faithful, on September 15th and on the first Sunday of every month, indulgences can be granted if the conditions required by the Church are met. The Sanctuary of Holy Water was also distinguished by John Paul II in his words.
The first documented information about the Sanctuary of Holy Water in Wasilków appeared in 1719. It is during this period that the popular legend took root. It is said that a man who had been blind for two years washed his eyes in the local spring and regained his sight. According to historical documents, this man was a nobleman named Bazyli Samotyja Lenczewski. After this miraculous event, he decided to give thanks by erecting a wooden chapel at the site of his healing, which stood right above the spring.
Over the years, the Sanctuary of Holy Water has undergone numerous destructions and renovations. The Prussian, Russian, and Napoleonic wars took a toll on the chapel, but it was consistently restored. After one such renovation, Bishop Josaphat Bułhak dedicated the sanctuary to the Seven Sorrows of the Blessed Virgin Mary. World War II also did not spare the chapel, which was not only destroyed but also partially burned. The reconstruction took many years. In the year 2000, the Hill of Crosses was created, with the Jubilee Pilgrim's Cross and crosses in the church that were blessed by John Paul II. As recalled by the portal turysci.pl, the Holy Father highlighted this place by saying, "Holy Water washes away the shores."
