San Guillermo Parish Church is located in the town of Bacolor, Pampanga, Philippines. It was originally built in the 19th century and is known for its beautiful Baroque architecture. The church has been a significant religious site for the local community and has undergone several renovations over the years. The church is particularly famous for its unique feature of being partially buried due to the lahar flows from the Mount Pinatubo eruption in 1991. This event led to the church being a symbol of resilience for the people of Bacolor, attracting both locals and tourists interested in its history and architecture.
