# San Juan, Ilocos Sur

San Juan, officially the Municipality of San Juan (Ilocano: Ili ti San Juan; Filipino: Bayan ng San Juan), formerly called as Lapog, is a municipality in the province of Ilocos Sur, Philippines. According to the 2020 census, it has a population of 26,674 people.
The town was named in honor of its patron, St. John the Baptist. As it produces the most number of goods made of buri leaf in the province, it is sometimes called the "Buri Capital of Ilocos Sur".

## History

The town was established in 1772 as Lapog. Over the years, the name of the municipality went through a series of changes. The early settlers and occupants called it "Lapo", short for "Lapo-Lapo", a tall grass which grew everywhere in the area. In 1772, Don Tomas Aquino, the first local leader, initiated the organization of the scattered communities into one, calling the place "Lapog", a derivative of local vernacular "Lap-Lapog" which means unirrigated land.
It was stricken by all sorts of plagues and epidemics (like the smallpox epidemics of 1808 and 1918–19, locust infestation in 1903, and destruction of ricefields by worms called "arabas" in 1905). Bessang Pass, just south of the poblacion, was constructed in 1874. Americans destroyed their town hall in 1903. But despite these misfortunes, San Juan progressed into a prosperous community.
For 189 years, "Lapog" remained in the records as the official name of the town until June 18, 1961, when Republic Act No. 3386 was enacted to rename the town, "San Juan". Since most of the inhabitants were of the belief that religious names bring peace, happiness, and prosperity, the town was renamed "San Juan", after the name of its patron saint, Saint John the Baptist.
