Father Antonio Muro was among the first to shape the settlement, leveling a portion of the hilltop to build a chapel on the spot now occupied by Puerto Princesa's Roman Catholic Cathedral and Rizal Park. By May 1872, the port had become the center of Spanish naval operations in the region -- its bay deep enough and sheltered enough to meet every requirement the navy set. Royal decrees offered incentives to settlers, and within a decade the town had twelve roads, a hospital, and a well-built port. By 1894, government authorities recognized Puerto Princesa as one of the most beautiful towns in the Philippines, citing the orderly arrangement of its streets, buildings, and houses. The American administration that followed made the city the seat of the Palawan Provincial Government in 1911, cementing its role as the island's administrative and commercial heart.

World War II nearly erased Puerto Princesa from the map. Japanese troops landed and occupied the city on May 18, 1942, and for most of the occupation the town was largely abandoned by its civilian population. The darkest chapter came at the Filipino Constabulary barracks, where Japanese forces perpetrated the Palawan Massacre -- an atrocity against American prisoners of war that became one of the most infamous episodes of the Pacific campaign. Liberation came with the Allied invasion of Palawan, but the city that reemerged in the postwar years had to rebuild almost from scratch. Barrios were reorganized, new municipalities carved from Puerto Princesa's territory, and the long process of restoring civic life began.

Puerto Princesa became a city in 1970 and a highly urbanized city in 2007, but its defining modern identity crystallized around a single natural wonder. The Puerto Princesa Subterranean River National Park, an 8.2-kilometer underground river that flows through a limestone cave system on Palawan's western coast, earned UNESCO World Heritage status in 1999 and was voted one of the New Seven Wonders of Nature in 2012. The campaign to secure that distinction became a national effort, with President Benigno Aquino III personally urging 80 million cellphone subscribers to vote. Today the city brands itself as the Philippines' "Eco-Tourism Center," serving as the jump-off point for Tubbataha Reef, Honda Bay island-hopping, and the underground river tour. Its population of over 316,000 reflects waves of migration from across the Philippines, creating a melting pot where Tagalog, Cuyonon, Hiligaynon, and English intermingle.

Among the original inhabitants of the Puerto Princesa area are the Cuyonons, who carry a rich legacy of folklore and traditions. Indigenous groups including the Tagbanwa, Palawano, Molbog, and Batak peoples each maintain distinct cultures and belief systems that predate Spanish arrival by centuries. This diversity gives Puerto Princesa a cultural texture uncommon for a city of its size, where a Vietnamese Buddhist temple built by refugees from the Indochina crisis sits not far from the Catholic cathedral, and where Maranao traders from Mindanao conduct business in the same markets as Visayan fishermen. The city's international airport connects it to Manila, Cebu, Davao, and Iloilo, while ferries link it to Coron, Cuyo, and the broader Philippine archipelago. Puerto Princesa remains what it has been since those Spanish sailors first rowed ashore: a port city at the edge of wilderness, looking outward from the last frontier.
