Bonfire

Wikipedia - "A bonfire is a controlled outdoor fire used for informal disposal of burnable waste material or as part of a celebration. Celebratory bonfires are typically designed to burn quickly and may be very large. The name 'bonfire' is from 'bone-fire'. In many regions of continental Europe, bonfires are made traditionally on 16 January, the solemnity of John the Baptist, as well as on Saturday night before Easter. Bonfires are also a feature of Walpurgis Night in central and northern Europe, and the celebrations on the eve of St. John's Day in Spain. In Finland bonfires are tradition on Midsummer Eve and Easter, also in midst of May celebrations."
