Alte Wallfahrtskirche - Credit: Wikimedia Commons
A pilgrimage to a statue of Mary in Werl, North Rhine-Westphalia, Germany, caused the building of pilgrimage churches there. The first one, completed in 1662, was replaced by a Baroque building completed in 1789, which later became known as the Alte Wallfahrtskirche (Old Pilgrimage Church). When it became too small, an adjacent Wallfahrtsbasilika (Pilgrimage Basilica) was built, dedicated to the Visitation (MariƤ Heimsuchung). It was declared a Basilica minor in 1953.
