Its original name was Salog or Saro. It was also referred to as "Ilaya" or "mountain/dry land" together with La Paz which was referred to as "Ilawod" or "sea/wet land". It had been one of the richer areas of Iloilo City even during the Spanish colonial period (1521–1898) and probably the richest town of the entire colony. Historical artifacts indicate that it had once conducted trade with China and Siam (Thailand) due to its port along the navigable river that ran through the town. It was also the center of religious and economic power in the Visayas during the Spanish rule.
