An army of towering trolls is on the loose in Denmark! Standing about 20 feet tall, they lurk in outdoor spaces across the European country, ready to surprise anyone who crosses their path.
But these fairy-tale giants mean no harm. They are sculptures made from recycled materials by eco-artist Thomas Dambo. Known for turning trash into treasure, Dambo uses everything from chunks of plywood to old fences to build art exhibits around the world.
