Every fourth Saturday in January, the 'biggest' bonfire in the world is lit to commemorate a dispute between two religious groups which, when the mediations failed, an entire mountain was set ablaze. Another theory behind the burning claims that the fires were set to drive away wild boars.
The ceremony begins with the lighting of torches which are carried in a parade to the foot of the mountain (an extinct volcano) and a large bonfire is lit part way up the mountainside, just past the barrier restricting access to the public. A spectacular firework display heralds the start of the event when the dry grass is set alight.
The spectacle can last from between 30 minutes to an hour depending on how dry the grass is and can be seen for miles around.
The first reader to write in and tell us in what country this event takes place, the name of the mountain and the festival will receive a prize.
Send your answers by email to email@example.com and put 'Where in the world?' in the subject line. Please include your full name, address and contact number so we can get the prize to you.
Last month's photo was of the Brighton or Royal Pavilion, a seaside retreat built for the Prince Regent, George Prince of Wales, who later became George IV. The link was to 'Burning the Clocks' on 21 December to mark the winter solstice. The event consists of a family lantern procession to the beach followed by a firework display. Congratulations to Sonia Ward in La Viñuela who was the first to answer the question correctly. A prize will be on its way.
