Among the seven pilgrim churches you understand those churches of Rome, whose visit was expected from an early Christian pilgrim travelers. They were all within one day walk and all the pilgrim´s indulgences were promised.
Over the years, this tradition has been more and more neglected until it was revived in the 16th century by St. Philip Neri. He invited several times a year, especially during Carnival and Easter, the people of Rome and the pilgrims to the Eternal City to participate on his pilgrimage to the seven main churches of the city. First, he was followed by ordinary people, while later he also won nobles and high clergy to his cause.
