The traditional Jar Making industry in Vigan is believed to have been introduced by the Chinese traders in the 14th century to provide an all-weather container or vessel for fermenting Vinegar, basi or wine (from sugar cane extract) and salt and for transporting these local products, along with the exotic goods from neighboring Asian kingdoms through the coastal sea lanes from Vigan to Cagayan and Vigan to Pangasinan – Manila on board Pontin sail boats. The factories had to be established in “Pagbantayan” (the old name of the barangay now called Pagburnayan) because of its accessibility to the rich clay deposits in Ayusan and most of the western barrios
Calle Crisologo, named after Don Mena Crisologo, the first Civil Governor of Ilocos Sur during the American regime was the commercial district of Vigan during the Spanish and early American period. The old name of this district is “Kasanglayan” or place of the Chinese.The houses all along the street served a double purpose then, the ground floor were occupied by shops (mostly owned by the Chinese) that sold dry goods while the second floors functioned as residences. Now the ground floors of the houses were converted into shops, catering to the tourist trade by their offerings of souvenirs, furniture, and genuine antiques and samples of authentic Ilocano weaving in different kinds of “Abel” cloth.
