The "bahay na bato" was constructed out of brick and stone rather than the traditional bamboo, timbre and other wooden materials that elevates the house. It is a mixture of native Filipino, Spanish and Chinese influences. During the 19th century, wealthy Filipinos built some fine houses, usually with solid stone foundations or brick lower walls, and overhanging, wooden upper story with balustrades and capiz shell sliding windows, and a tiled roof. Excellent preserved examples of these houses of the illustrious Filipinos can be admired in Vigan, Ilocos Sur. Preserved examples of "bahay na bato" are also found in Taal, Batangas and Boac, Marinduque in southern Luzon, Iloilo, Iloilo and Carcar, Cebu in the Visayas, and Dapitan, Zamboanga del Norte.
