From OSV News:
A Marian sanctuary in the heart of northern Europe’s countryside — often called the “Polish Lourdes” — could soon draw global attention, as Pope Leo XIV has been invited to visit the site where the Virgin Mary appeared approximately 160 times.
As the Marian month of May unfolds, the village of Gietrzwald (pronounced Gyetsh-vowt), in the picturesque northeastern Warmian-Masurian lake region — is preparing for major celebrations in 2027 marking the 150th anniversary of the apparitions. Polish bishops, along with President Karol Nawrocki, who visited the Vatican in September 2025, have extended an invitation to the pope, raising the possibility that the quiet sanctuary could become the focus of international pilgrimage and renewed Marian devotion.
