The Old Jaro Municipal Hall is a heritage building in the centre of Jaro district, preserved from the period when Jaro functioned as its own autonomous municipality rather than a district of Iloilo City. The Spanish colonial architecture — solid masonry walls, arched openings, and a prominent facade — reflects the civic ambition of a town enriched by the 19th-century sugar boom and the land holdings of its ruling families.
The building is one of several formal civic structures in Jaro that survive from the colonial period, including the nearby cathedral and belfry. Together they give the district a coherent historical character quite different from the commercial downtown of Iloilo City proper. The hall stands at the edge of the main Jaro plaza, and the surrounding streets have enough surviving colonial architecture to reward a slow walk. Jaro's heritage is somewhat overshadowed by better-known Philippine colonial sites, but it is one of the more intact examples of a Filipino provincial town at the height of the sugar era.
