Casiguran, Aurora
Casiguran, officially the Municipality of Casiguran ( Tagalog/ Kasiguranin: ''Bayan ng Casiguran''; ilo, Ili ti Casiguran), is a 2nd class municipality in the province of Aurora, Philippines. According to the 2020 census, it has a population of 26,564 people. The municipality is home to the Amro River Protected Landscape. Etymology According to folk legend, the name Casiguran was obtained from the Ilocano term ''Sigod'' which means "edge" or "maximum", which is due to the location of the Municipality at the northern edge of Aurora Province. (Another translation & definition of ''sigod'' is "soon" or "early") Another legend says that if an unmarried stranger comes to the place, he unavoidably falls in love and marries and most of the time stays for good. The affixation of ''sigod'' when converting it to a noun is ''kasigudan'', from which the Hispanized pronunciation "Casiguran" is derived.

The Franciscan missionaries henceforth dedicated the district to Saint Anne, the mother of the Blessed Virgin Mary, and called it ''Santa Ana de Sapa'' ("Saint Anne of the Marshes").
