It is bounded on the North by Aggay, Puspus and Sinabaan, on the East by San Isidro, on the West by Cabaroan; and on the South by the City of Vigan and a tributary of the Abra river, colloquially known as San Julian river. At the height of torrents, the Barangay is literally detached from the rest of the town because the read leading thereto become impassable. 

        How the name of the barangay originated is not known, but as could be gleaned, it was in honor of its patron saint, San Julian. It has a registered voter of 448 and Barangay San Isidro (formerly known as Sitio Piano) used to be one of its sitios but due to administrative demands, it was constituted as a separate barangay unit (at preceding page).

        Its residents depend on agriculture for their subsistence.  Their produced includes rice, corn, peanut, tomato, sugar cane, onion, string bean and other backyard vegetables.  Some are into livestock raising. It is situated in a low lying area that is often inundated brought about by the river that crosses its path of territorial jurisdiction.
