Iloilo Central Business District

The Iloilo City Central Business District (Filipino: Distritong Pangkomersyo ng Lungsod ng Iloilo), commonly known as the Calle Real Heritage Zone and colloquially as Old Downtown Iloilo, is a historic commercial district located within the larger district of City Proper in Iloilo City, Philippines. It served as the city's center of commerce and culture from the Spanish colonial period through the American era and into the postwar years. The district encompasses major thoroughfares such as Calle Real and Iznart Street, along with minor surrounding roads including Aldeguer, Guanco, Mapa, Ortiz, and Rizal Streets. It is notable for its concentration of neoclassical, beaux-arts, and art deco architecture dating back to the colonial period.

In 2013, the heritage zone has been declared as one of Iloilo City's Cultural Heritage Tourism Zones along with Plaza Jaro Heritage Zone, Plaza Molo Heritage Zone, Plaza Libertad, and Fort San Pedro through Republic Act Number 10555.

In 2014, the National Historical Commission of the Philippines (NHCP) declared the area a heritage zone under Resolution No. 3, s. 2014, in recognition of its historical and architectural significance. It is also being proposed by the UNESCO National Commission of the Philippines for inclusion in the country’s tentative list of future UNESCO World Heritage Sites, under the title "Historic Center of Iloilo City (Calle Real)" as part of the serial nomination "The Sugar Cultural Landscape of Negros and Panay Islands".
