Pilgrimage, as a type of religious journey, involves embodied movement across geographic, social, political, cultural, and often religious boundaries to a sacred place or landscape. It is arguably a universal phenomenon that can engage individual pilgrims or millions, especially with the onset of modernity, which has facilitated travel over distances great and small. As an aspect of religious life in the United States, pilgrimage is often overlooked. Nevertheless, the country’s landscape encompasses numerous sites of sacred significance associated with organized religions, civil religion, and facets of its cultural religion that attract millions of visitors annually. As a dynamic set of phenomena, pilgrimages to such sites are constantly evolving, affected by factors such as religious and social movements, national politics, immigration, and tourism.
