Valencia’s history begins with a small settlement called Ermita, which means "secluded place" in Spanish. This name was no coincidence: nestled in the mountains, it served as a safe haven for local residents. The official history of the town as an administrative unit began in the 19th century when Spanish influence grew, leading to several name changes over the years.
- 1856: The settlement was renamed Nueva Valencia (New Valencia) in honor of the parish priest, Matías Villamayor, who hailed from Valencia, Spain. The name "Valencia" itself comes from the Latin word Valentia, meaning "strength" or "valor."
- 1920: The name was changed to Luzuriaga in honor of Don Carlos Luzuriaga, a Filipino politician who promised to help develop the town.
- 1948: The town's current name, Valencia, was officially restored.
Valencia’s development was largely shaped by its unique geography. Its position on the slopes of Mount Talinis not only provided protection but also created a distinct cool climate, earning Valencia the nickname "Little Baguio" of Negros. The influence of Spanish clergy and later local leaders led to the construction of roads and water systems. Notably, an old Spanish fountain can still be seen in the town center; it once served as the primary water source for residents. During mid-20th-century historical events, the area also served as an important hub for local resistance, as documented in local museums.
Originally, Valencia was primarily an agricultural center. Residents successfully grew various crops, including the famous lanzones fruit, which was exported to neighboring regions. Religion has always played a vital role in town life. The patron saint of Valencia is Our Lady of the Abandoned, to whom the main church is dedicated, and her feast day is celebrated annually on October 12th.
