Visita Iglesia is a Spanish phrase which means visiting churches. The original Filipino Catholic tradition is a Holy Thursday event after the Last Supper celebration wherein the faithful visits the exposed the blessed sacrament in seven chosen churches for veneration until midnight.
However, some faithful use also this term in visiting churches aside from the time mentioned above as long as it is within the time of Lenten season. Some church official would like to use term Parish Pilgrimage instead.
Whatever might be the term used, one thing is sure it is a religious activity that the Catholic faithful see as an act of piety that strengthen one's faith.
Here is one of the route of the Parish Pilgrimage of the St. Martin de Porres parishioners from Adelina 1, San Pedro, Laguna, Philippines. It includes the map and prayer of the station of the cross.
