Calapan, officially the City of Calapan (), is a component city and the capital of the province of Oriental Mindoro, Philippines. According to the , it has a population of people, making it the most populous settlement in the entire island of Mindoro.
Calapan is the regional and administrative center of the MIMAROPA region as well as its second largest city in the region, after Puerto Princesa in Palawan. It is the only city on the island of Mindoro and one of only two cities in MIMAROPA.
The city also serves as the primary center of commerce, industry, transportation, communication, religious activities, and education in the province of Oriental Mindoro.
The city serves as a primary gateway to Oriental Mindoro, a role enhanced by the Strong Republic Nautical Highway (SRNH) network. Its main maritime hub, the Port of Calapan, is the busiest seaport on Mindoro Island and is located 45 minutes to 3 hours from the Batangas International Port via ferry or roll-on/roll-off (RORO) vessels. Additionally, the port features the largest passenger terminal building in the Philippines and records the highest passenger volume in the region, catering to millions of travelers annually.
Etymology The derivation of the name of Calapan cannot be traced with certainty.
Some have suggested that it comes from the word “Kalap,” meaning to gather logs, implying that “Kalapan” was a place where logs were collected. However, historical records do not mention Calapan as a center for logging, and the town’s swampy environment would not have supported the growth of large forest trees suitable for timber.
Another theory states that Calapan was originally pronounced “Kalapang,” which, according to an old Tagalog dictionary, is a synonym for “sanga” (branch) or “a part of anything.” This could refer either to the settlement being a branch of its mother town, Baco, or to the peninsula where the Calapan seaport, airport, and the barangays of Lazareto and San Antonio are now located.
History
Early History Prior to Spanish colonization, the island of Mindoro was inhabited by the Mangyan people, one of the earliest indigenous groups in the Philippines.
The island also functioned as a regional trading hub, with Chinese merchants documented to have engaged with local communities as early as the 10th century. This interaction is often associated with trade between the pre-colonial polity of Ma-i and merchants from what is now Guangdong in southern China. The precise location of Ma-i remains a subject of scholarly debate.
With the expansion of Spanish colonial authority, segments of the indigenous population relocated from coastal settlements, including areas corresponding to present-day Calapan, to the interior highlands. This movement is generally understood as a response to colonial intrusion and the increasing pressures of external settlement and control.
Spanish Colonial Period Calapan was formerly a small village before the establishment of the first Religious District in Baco. The District convent was transferred to Calapan in 1733 and began its jurisdiction over the Northern Mindoro Ecclesiastical Area.
The town’s poblacion, or town center, was originally located slightly inland in what is now known as Lumangbayan, meaning “old town.” Presumably due to pirate raids in 1753-1754, the poblacion was later relocated to its present site along the coast of Calapan Bay.
During the early 18th century, the town occupied a narrow strip of land extending from Ibaba to Ilaya, laid out in a cross-shape facing the present Santo Niño Cathedral and divided by a river. Over time, additional barrios were established to accommodate the growing settlement.
At Ibaba, Augustinian Recollects constructed a church fortified with walls and watchtowers to protect the settlement from attacks from the south. Although the church was rebuilt in concrete at around the 1940s, remnants of the original fortifications, localy known as a kuta, are still visible in what is now the Oriental Mindoro Heritage Museum.
In 1837, the capital of the province was moved from Puerto Galera to Calapan. The 1800s census showed that Calapan had 979 native families and 8 Spanish-Filipino families.
Inspired by an earlier movement led by Juan Naguit of Cavite, in which a group of Filipinos attacked the church of Sucol (present-day Bongabong) during Mass on 22 May 1898, hundreds of Mindoreños—including migrants from Cavite and Batangas as well as members of the local elite—took up arms across the island.
In early June 1898, approximately 1,000 revolutionaries launched an assault on the provincial capital of Calapan, but the initial attack was repelled by Spanish forces. The revolutionaries succeeded only after the arrival of over 1,000 additional insurgents under Colonel Alfonso Panopio from Batangas, who joined forces with the local Mindoro fighters. On 1 July 1898, Governor Rafael Morales formally surrendered, and a revolutionary government was promptly established in Mindoro.
American Colonial Period The occupation of the Philippines by American forces following the defeat of the Spanish government in Manila brought significant political, economic, and social changes to the island of Mindoro and to the city of Calapan.
The occupation of Calapan by American forces began in earnest on 15 July 1901, when seventy U.S. soldiers disembarked near the town and took control with minimal resistance. During this initial occupation, several houses were burned, some residents were wounded, and twenty-five Filipinos were killed. According to the diary of Pedro del Rosario, a local schoolteacher at the time, some victims were forced into the river in groups and shot. After this expedition, the Americans returned to Batangas.
A second, larger expedition commenced on 27 July 1901, with 800 U.S. soldiers under the command of Major Evans tasked with occupying Mindoro permanently. The mission also included an objective to capture or neutralize Arthur Howard, an American deserter believed responsible for the death of U.S. General Lawton in December 1900; however, this objective was not achieved, as Howard and Provincial Governor Ramon Atienza evaded capture by retreating to the forests.On 29 July 1901, Calapan was formally occupied by U.S. forces. Major Evans subsequently established a municipal government composed of Filipinos willing to collaborate. Pursuit operations against remaining Filipino soldiers were largely unsuccessful due to the swampy terrain near Lake Naujan, which provided a strategic advantage to the defenders.
A primary education system using English as the language of instruction was introduced, and Calapan Port was opened to facilitate inter-island commerce. The U.S. Army Signal Corps installed military telegraph lines connecting Calapan and Batangas, while land-based telegraph services were also made available to the public in Calapan and Naujan. The development of a provincial road along the east coast, which later became part of the Strong Republic Nautical Highway, connected the island’s main towns. Additionally, the implementation of free trade between the United States and the Philippines encouraged economic growth and attracted a significant number of settlers to the previously sparsely populated areas of Mindoro and the city of Calapan.
When Mindoro became a sub-province of Marinduque on June 13, 1902, the provincial capital was once again moved to Puerto Galera, with Captain Robert S. Offley serving as the first civil governor. On November 10, 1902, Mindoro was detached from Marinduque. In 1903, Calapan once again became the provincial capital.
When Mindoro was detached from Marinduque on November 10, 1902, Baco, Puerto Galera and San Teodoro were annexed to Calapan in 1905 under Act No. 1280, adding a total area of of land. In 1902, under Act No. 2824, the three municipalities gained their independence.
In 1919, the boundary dispute between Calapan and Naujan was settled by the presidents (mayors) Agustin Quijano of Calapan and Agustin Garong of Naujan regarding a portion of territory that now defines the present boundary. The agricultural area was awarded to Naujan, reducing the size of Calapan relative to Naujan, which is currently the largest municipality in the province by land area.
Japanese Colonial Period and the Battle of Mindoro
On 27 February 1942, Japanese forces under Colonel Kendo Suzuki landed in Barrio Silonay, Calapan, Oriental Mindoro, advancing into the town without resistance. Anticipating the invasion, Major Ramon Ruffy of the Mindoro Constabulary Company ordered a withdrawal into the hills. Lieutenant Alfredo Mendoza, who remained behind, was captured and became the first prisoner of war in Mindoro. In the early phase of the occupation, portions of Calapan, including the San Vicente district, were burned.
During the occupation, key civilian structures were repurposed for military use. The Mindoro High School compound served as a Japanese garrison and headquarters, while the Calapan Central School was converted into a barracks for Filipino constabulary units under Japanese command. The old Kuta functioned as a watch post and telegraph station. Nearby residential buildings were utilized for administrative and social functions. In response, local resistance movements emerged, notably factions led by Major Ramon Ruffy and Captain Esteban P. Beloncio.
The Allied invasion of Mindoro commenced on 15 December 1944, with American forces landing at Mangarin Bay in present-day San Jose, Occidental Mindoro. Owing to inadequate airstrip facilities in Leyte, the 503rd Parachute Regimental Combat Team was deployed by sea alongside the main assault force rather than by airborne drop. Following the landing, U.S. troops advanced northward across the island.
By 23 January 1945, American forces reached and liberated Calapan, encountering minimal resistance as Japanese troops retreated westward toward Baco and Mount Halcon. During their withdrawal, however, Japanese forces implemented scorched-earth tactics, destroying bridges and infrastructure and committing widespread atrocities against civilians. These included mass killings in locations such as Sitio Suqui and within the former Kempeitai headquarters. The violence and destruction left a significant loss of life and much of the town in ruins by the time of its liberation.
1994 Mindoro Earthquake
In the early morning of November 15, at 3:15:30 AM (PST), a magnitude 7.1 earthquake struck the Isla Verde Passage area, producing very strong ground shaking. The quake, associated with a 35-kilometer ground rupture along the Aglubang River fault, was felt as far as Manila, about 125 kilometers away.
The disaster resulted in 78 fatalities and damage to at least 7,566 houses. Calapan recorded 17 deaths, many of which occurred in the coastal village of Wawa. A significant number of the victims were children who drowned when a tsunami that struck shortly after the main shock.Earthquake Engineering Research Institute (EERI). (1995). Philippines: Mindoro Island earthquake of November 15, 1994 (Learning from Earthquakes report). Gathered from:
Within two to five minutes of the earthquake, a tsunami hit the northern shores of Oriental Mindoro and nearby islands. Witnesses described the wave as a fast-moving, white, curtain-like wall approaching from the sea, preceded by a loud roaring sound. In some areas, the sea briefly receded by about 50 meters before the waves arrived. The tsunami reached heights of up to 3–6 meters and penetrated 50 to 300 meters inland, devastating coastal communities.
