Jaro formerly known as "Salog is bounded on the north by Pavia and Mandurriao; on the east by Leganes, on the south by Lapaz and on the West by Molo. Th Salog and Dungon rivers course throught its plains.

      Jaro is located about five Kilometers from Iloilo City, the provincial capital of Iloilo. It was already an Independent Flourishing city long before Iloilo became one. In the Early twentieth century, the center of economic and political activity shifted to Iloilo which upon becoming a chartered city in 1937, it asorbed the former city of Jaro as the old towns of Arevalo, Molo, Mandurriao, and Lapaz. The loss of Jaro's independence as a city has not in any way diminished the impressive achievements she has accumulated throughout the centuries.

      During the Spanish period, her bureaucratic system was close to the ideal. She had rich agricultural lands and a thriving weaving industry. Her river ports were bustling and her market day, every Thursday, was always and still is a colorful sight to behold.

      Jaro was also the home of many geat men and women. This is no exaggeration when given a list of Jaro's illustrious children. To name a few: Graciano Lopez Jaena(great revolutionary hero), Jose Lopez Vito (editor of El Tiempo Fernando Lopez (former Vice-President of the Philippines), Eugenio Lopez (founder of Meralco), Gen. RefaelJalandoni (Hiligaynon poetess) and Gil Lopez Kabayao (renowned Violinist).

But more than her children's meritorious achievements in various fields of endeavor, Jaro's fame rests on her vibrant ecclesiastical history.
