Brief History

A. Origin of Name

The name “Iloilo City” was derived from “irong-irong”, a reference to the native word “irong” which means “nose”. The name took after the nose-like configuration of the main settlement area during the pre-Spanish period as so shaped by the Iloilo River. Chinese traders who frequent the area and who mispronounce the “r” sounds with “l” sounds, soon popularized the term “ilong-ilong” which later evolved into the current name Iloilo Arial 9.5 The name is said to have also evolved from a local fish of the same name which was indigenous to the place and which was a staple in the early inhabitants’ daily meals. Iloilo City was also referred to as the “Most Loyal and Noble City” or “La Muy Leal Y Noble Ciuded de Iloilo” in Spanish. This is an inscription in the Coat of Arms from the Royal Decree of 1896 in recognition of the local people’s loyalty to the Spanish crown.

History of Urban Growth of Iloilo City

Pre-Spanish Period

As with other civilizations, Filipino settlements began along bodies of water. In Iloilo, the typical dwelling was the hut made of bamboo and grass or palm, which lined up along the coasts or the banks of Jaro, Iloilo and Batiano Rivers. Rich landscape of forests, ricefields, mountains or brush and bamboo thicket provided the natives with materials for clothing, shelter and tools. The simple ways of Ilonggos were reflected in the lack of public buildings or places of worship.

Spanish Period

Under Spanish colonization the early type of dispersed settlement called barangays evolved into towns (pueblos) and provinces (alcaldias). Parish churches, beside the nearby town hall (casa tribunal) and town plaza, became the heart of town plans. From the town center, residences filled up the streets which radiated in a grid-iron pattern. Today, the town plaza remains a center of public and religious celebrations.

The seat of government was first set up along the coastlines of Arevalo, which was always under the threat of Muslim or Dutch pirates. Political survival prompted the Spaniards to transfer the seat to Ogtong (now Oton) and eventually near the mouth of Iloilo River (now Fort San Pedro). Since its establishment, a radial road network which radiates from the fort is still being used today.

American Period

In Iloilo, the American Period brought about further economic development through road networks. The British cannot only be credited for strengthening the booming sugar industry. In 1857, Nicholas Loney, the first British vice-consul in Iloilo, was responsible for the kilometer long Road Calle Progreso (now Isidro de Rama Street), which linked the warehouse (bodegas) of sugar with the Iloilo towns. Loney also led the gradual reclamation of the whole western bank of the river and eventual relocation of the business center to the nearby Calle Real (now J.M. Basa Street).

The 1920s witnessed the introduction of the working class districts (barrio obreros) to accommodate the low-income labor sector. Barrio Obrero was established in Lapaz to the north of the Iloilo River’s mouth. During this time, Art Nouveau and Neo-Colonial architecture also flourished in the city’s downtown. Typical designs were arcaded ground floors set back in near straight alignments.

Although Manila was the focus of planning then, Iloilo was elevated as chartered city on 16 July 1937. During this time, Ilonggos, who received American grants to study architecture abroad, returned and brought American architecture to their homes. Usual Commonwealth elements were the eagle, scroll and olive leaves.

By the end of World War II, Iloilo’s blooming economy was in ruins. The decline in sugar economy and exodus of people and investors to other cities such as Bacolod and Cebu, led further to its economic demise.

Iloilo gradually recovered as the planning focus was on reconstructing and reviving war-torn Philippines. In 1959, Iloilo City joined other chartered cities in implementing the urban planning strategies and policies of the National Planning Commission.

Modern Period

The next three decades saw the moderate growth of Iloilo City with the establishment of fish ports, an international seaport, and other commercial firms. Iloilo City also became the Regional Center of Western Visayas.

In 1977, a Comprehensive Urban Development Plan for Iloilo City was approved and was adopted by the Sangguniang Panlungsod. The Land Use Plan and Zoning Ordinance was the implementing tool. However, the 1977 Plan was unable to cope with the demands of rapid urbanization.

By the end of 1993, a multi-sectoral group prepared the 1994-2010 Comprehensive Development Plan of Iloilo City to amend the old plan and address the present and future challenges of urban development. The plan, however, was not carried pending the approval of the Housing and Land Use Regulatory Board (HLURB).
