The devotion to Lolo Uweng in San Pedro Tunasan, Laguna, traces its origins back to the 1730s when a visita was established in the sitio of Landayan. The devotion gained prominence in the 19th century after a miraculous image of the dead Jesus was reportedly found on the shores of Laguna Lake. As news of the image's miraculous powers spread, people from surrounding areas began visiting the chapel, and the image became known as Lolo Uweng, a term derived from "Emmanuel Salvador del Mundo," meaning "Emmanuel, Savior of the World." The small chapel, initially built with bamboo and cogon, was replaced with a more durable church structure after World War II.

In 1969, the parish was canonically established, adopting the title of the Santo Sepulchre (Holy Sepulchre), and expanding during the 1980s to accommodate a growing number of worshippers. Several subparishes were formed within its jurisdiction. As devotion to Lolo Uweng continued to increase, the parish was elevated to a Diocesan Shrine on December 1, 2006, by Bishop Leo Drona, SDB. The shrine has since become a significant pilgrimage site, drawing thousands of devotees, especially on Fridays during Lent and Holy Week, offering spiritual nourishment to people from Laguna and neighboring provinces.
