“Ribsuan” was used to be the name of the place when it was one of the barrios that were organized into a municipal district of Burgos of the Province of La Union by virtue of Executive Order No. 54 issued by then Governor General Leonard Wood on November 27, 1925.  Barrio Ribsuan then extends over the Ribsuan River to some portions of the present Ribsuan of Naguilian, La Union up to Agiwas and the vicinity of Don Tomas Elementary School in Sili.  The seat of the Municipal District Government was then in this barrio with a town hall made of bamboo and cogon built at present location of Burgos Central School.  When rivers and creeks were established as municipal boundaries, Ribsuan was annexed to Naguilian, La Union and the seat of the district government was transferred to the Central, where again, a town hall or “presedencia” was constructed by the people out of bamboo and local materials and was located just as few meters away southwest from the present barangay plaza.  Being then the seat of the municipal government, the barrio was called “Central” and or “Poblacion”. When the “Presidencia” was transferred to Bilis in 1960, Central was then used to be called “Nagpanaawan”.  It was then in 1968 that Central or “Nagpanawan” was officially named as “Old Poblacion” due to the creation of Barangay New Poblacion (where the Municipal Hall now stands) which weaned from mother Barrio Bilis by virtue of Provincial Board Resolution No. 531.

            Barangay Old Poblacion is bounded on the East by Barangay New Poblacion; on the West by the Ribsuan River (Naguilian); on the North by Barangay Caoayan; and on the South by Barangay Agpay.  It occupies an area of 106.9864 hectares with a population of 511 (in 2015).  Bisected by the Baguio- Bauang National Road, it can be reached from Baguio City and San Fernando City in an about an hour-ride and 45 minute-ride, respectively.

            Early settlers of the place came from various municipalities and province, like: Vigan, and Candon, Ilocos Sur; and Naguilian, Sto. Tomas and San Fernando of the Province of La Union.  At present, about 99% of its residents are Ilocanos due to the coming of some people of different ethnic origins to live with them.

            Practically, the place maybe considered as an agricultural area. While some of the residents’ source of income is farming, many are engaged in various kinds of small scale business enterprises and other livelihood activities.  Most of the residents are employed in professional jobs and other skilled works.

            A Roman Catholic Church (Our Lady of Fatima Parish Church) stands in the barangay which signifies that the community people are predominantly Roman Catholics.  It is in the barangay where the oldest elementary school in the Municipality was established.  It is also where DECS- Burgos District Office is located.

            The Barangay has its own barangay plaza, barangay hall and a barangay clinic. It has also a 0.770 kilometer- barangay road that caters most of the residents of Caoayan, Lower Tumapoc and some residents of Casilagan, Naguilian, La Union.

            During its infancy, it was ruled by dedicated and clever “Tenientes de Barrio” like: Valencio Martinez, Esteban Antonio, Bernardo Gallardo and others.
