The Vigan Heritage Village is a town in Vigan, Ilocos Sur that is considered the best-preserved example of a planned Spanish colonial town in Asia. In November 1999, it was placed on the World Heritage List commemorating its cultural significance. The village was established in the 16th century. The name "Vigan" was derived from a giant taro plant "biga" that grew abundantly along the riverbanks. Most of the materials -- such as adobe, pebbles, bricks and posts -- were brought from Europe through the Manila-Acapulco Galleon Trade. The construction work was done by Chinese laborers. Thus, the village's architecture reflects a unique fusion of Spanish European and Chinese culture.
