During the penultimate pilgrimage to Poland in 1999, Pope John Paul II visited the Sanctuary of Our Lady of Studzieniczań. On the island, next to the chapel, a monument by Czesław Dźwigaj commemorating this visit was erected in the place where he came by the white fleet. The sanctuary is associated with the apparitions of the Virgin Mary, which took place in the 18th century. Currently, it is the main place of Marian devotion in the Ełk diocese.
