century is implied during by the sugar boom with ubiquitous stately mansions and edifices built by the old money Ilonggo Sugar Baron and elite families which contrast to the city's economic importance as a second city next to Manila during the said era in the Philippines. The city's other moniker – City of Mansions is likewise implied because Iloilo holds 240 mansions in which 30 of it are grand mansions built during the Spanish and American colonial eras. The ravaged Fuerte de San Pedro (Fort San Pedro) is Iloilo's ground zero as there was no Iloilo City back in the 1600s. As a fortress, Fort San Pedro was built solely by the Spaniards to protect Iloilo from the marauding pirates and privateers. The fort is the second Spanish built fort after the one in Cebu (also Fort San Pedro) in the Philippines and Asia. The foundation of the Fort San Pedro was substantial to the Spanish Empire's stronghold as Panay Island with Iloilo as their second colonial center established through the Iloilo precursor towns of Oton (1566) and La Villa Rica de Arevalo (1581). Oton which was founded as early as 1566 but formally established in 1572 was the actual second seat of Spanish colonial powers but due to pirate attacks, they moved the capital eastward and established the La Villa Rica de Arevalo. The town of La Villa Rica de Arevalo holds some of the fine example of Spanish built mansions like the mansion of the Spanish Governor General, but were destroyed when the pirates ransacked and destroyed the town. It was in the said frequent events of pirate attacks that the Spaniards moved finally the capital further eastward in the mouth of Rio de Iloilo (Iloilo River) which is flanked and protected by Guimaras Island across it. It was in the said establishment of the city on the mouth of Iloilo River that as years go by, the city flourished to its heights especially in the economic and regal importance in the Spanish and American eras. La Villa Rica de Arevalo (Arevalo) is the first Spanish named town in the Philippine islands. It is also in Arevalo that the third oldest image of Holy Child Jesus (Señor Santo Niño) in the Philippines was brought by the Spaniards. Notable present-day structures that are repositories that attest to the town's former glory as a Spanish precursor town of Iloilo is
