A parol is a Filipino ornamental lantern displayed during the Christmas season. Parols are traditionally constructed using bamboo and Japanese paper, and are illuminated with candles, oil lamps, or carbide lamps. Modern parols can be made using other materials such as plastic, metal, and capiz shells and are usually illuminated with electric lighting. Its most-common form is a five-pointed star, although it can come in various shapes and sizes. Large disc-shaped electronic versions of parols produced in Pampanga are known as "parul sampernandu", the phonetic spelling of parol San Fernando, owing to the city where these lanterns are a major product.
