How a Philippine town built on volcanic hot springs became a global science hub
In short: Known as the baths, Los Baños sits between a dormant volcano and a massive lake. While its thermal waters once drew Spanish friars to build healing centers, the town evolved into a dense academic enclave, hosting international research institutes that fundamentally changed global agriculture and nature conservation efforts.
The identity of Los Baños is inseparable from its volatile geology. Nestled on the northern slopes of Mount Makiling—a potentially active volcano—and the shores of Laguna de Bay, the town is defined by geothermal activity. The name itself, meaning the baths, was adopted in 1589 when Franciscan friar Pedro Bautista established public bathing facilities. By 1590, the Franciscans had founded a hospital dedicated to the Virgin of Holy Waters, marking the beginning of a settlement pattern centered on the town's natural thermal springs.
Over the centuries, the town transitioned from a colonial religious outpost to a center of intellectual and scientific life. The establishment of the University of the Philippines College of Agriculture in 1909 laid the groundwork for this shift. During the 1960s, the town gained international prominence when the International Rice Research Institute developed IR8, a high-yielding rice variety that significantly boosted production across the Philippines. Today, Los Baños is considered one of the densest habitats for academics in Southeast Asia, housing institutions like the ASEAN Center for Biodiversity.
The town's history is also marked by dramatic turbulence. During World War II, the university campus served as a Japanese prisoner of war camp until a daring 1945 raid by US forces and Filipino guerrillas liberated over 2,000 Allied nationals. Later, during the martial law era of the 1970s, the town became a site of significant student activism and political unrest. Despite these challenges, Los Baños was officially designated a Special Science and Nature City in 2000, recognizing its ongoing role as a hub for collaborative research in agriculture, forestry, and life sciences.
Geographically, the landscape remains a defining feature. Five rivers, including the Molawin and the Dampalit, traverse the town, feeding into the lake. Nearby, the maar lake known as Tadlac—or the enchanted lake—serves as a reminder of the region's volcanic origins. With a 2024 population of 117,030, the municipality continues to balance its role as a popular tourist destination for hot spring resorts with its status as a critical node in global scientific development.
