Barangay Sasaba is bounded on the south by San Gabriel. It is next to Puguil in terms of land area at 1,238 hectares with 6 sitios namely: Bay‐o, Tico, Bacayawan, Gambang, Potrido and Tebac.

The barangay could be reached by vehicles through the Poblacion- Ramot-Sasaba road or via Lon‐oy, San Gabriel during summer time. During rainy season, people carry their products to the Poblacion on foot through the Kamamba‐ey Route.

Sasaba was so called due to the abundant banana fruits in the place. Sitio Bay‐o, the uppermost barangay and the gateway to the next barangay, Sapdaan, came from the two big mountains between it which form like a mortar.

Gaoagao, Bacayawan, Tebac were organized as sitio during the Spanish Rule under Mt. Province. In 1920, these sitios became part of La Union under San Gabriel. Later the boundaries of Santol were extended to include these when it became a municipal district.

Tico means something that is divided in the local dialect. Once it was a wilderness conducive for hunting but Kaingin divided the wilderness into small forests, hence the name Tico from present state of barren hills and mountains in the area.

In the 1930’s, Christians began settling in Sitio Gambang. It was the residence of blacksmith famous for collecting cans. Whenever he go, he gathers cans which people called “gambang“. Whenever people go to the place, they gave him “gambang” and from his death, the name remains until now. At sitio Manabong, negritos became the first settlers but they did not build their shelter.
