Orion, Bataan

The town of Orion has various etymologies. One theory suggests that the town was initially called "Udyong," derived from the words "lu-ad" and "uryong," meaning muddy or swampy.

Another popular story states that during the Spanish colonial period, a group of soldiers passing through the area asked locals for the name of the place. Mistaking the question, the residents responded with "uod yon," which referred to a worm on the ground. The soldiers assumed it to be the name of the town and left, murmuring "uod, uod yon." Eventually, the town came to be known as Udyong, which was later changed to Orion.^[6]

Orion's official recognition date is unknown, but records indicate that it was established by a Dominican priest on April 30, 1667. The 1818 Spanish census showed there to be 1,336 native families and 8 Spanish-Filipino families.^[7]: 357 On September 16, 1852, an earthquake struck the Philippines and destroyed the parochial church in Orion. The church was later reconstructed by Fr. Ulpiano Herrera, the parish priest at the time. A major fire ravaged the town in 1892, leaving only three houses unscathed. Fr. Jose Campomanes led the effort to rebuild the town, which transformed it into a thriving and attractive community.^[8]
