Ålesund, Norway, is the site of a Midsummer Festival called Slinningsbålet that traditionally includes a bonfire. The bonfire tends to be bigger each year, and this year’s stack of pallets and kindling was 155.5 (47.4 meters) feet tall! That’s a world record. The structure is built by hand on a spit of land out in the bay, and fire department boats stand by for safety. The fire is lit at the top, which means someone has to climb all the way up, and then all the way back down in a hurry. You can see a video of the tower’s construction and destruction here. The burning begins about four minutes in. -via Atlas Obscura
