Esposo Ancestral House is a Registered Property, Municipality of Paoay, Ilocos Norte located at Paoay, Ilocos Norte, Region I.
Touted as the biggest house in Paoay prior to the war, the present-day Esposo ancestral house is a relocated house from an adjacent lot that was lost to the Borja (later on to the Pobre) via a court ruling. The present house retains the front half of the original house, hence the current size is half of what it used to be. Relocation was finished in June 15, 1970 as commemorated on an engraving by the pain portal. The house is made of hardwood, mostly mahogany and narra, has capiz windows and ventanillas with wrought iron grills, as well as two extended iron lamps on both corners in front. It was the house of three generations of Gobernadorcillos of Paoay: Juan Esposo, Buenaventura Esposo, and Elueterio Esposo - grandfather, father and son, respectively. Francisco Claros Esposo, son of Elueterio, was also one of the first who practiced medicine in town
