The Christian Church traditionally observed Hallowe'en through a vigil. Worshippers prepared themselves for feasting on the following All Saints' Day with prayers and fasting. This church service is known as the "Vigil of All Hallows" or the "Vigil of All Saints"; an initiative known as "Night of Light" seeks to further spread the "Vigil of All Hallows" throughout Christendom. After the service, "suitable festivities and entertainments" often follow, as well as a visit to the graveyard or cemetery, where flowers and candles are often placed in preparation for All Hallows' Day. In Finland, because so many people visit the cemeteries on All Hallows' Eve to light votive candles there, they "are known as "valomeri", or seas of light".
