Giant trolls have a message for humans about protecting the planet
July 23, 2025
Danish artist Thomas Dambo creates giant wooden trolls from recycled materials to promote environmental awareness. Over 12 years, Dambo and his team have built 170 trolls in more than 20 countries and 21 U.S. states. These sculptures, some up to 40 feet tall, are made from discarded items like wooden pallets and old furniture. An installation of six trolls, called “Trolls Save the Humans,” is currently on display at Filoli, a historic estate near San Francisco. Dambo says the trolls aim to teach humans how to live sustainably. Dambo said his global project attracts millions of visitors annually, highlighting the value of recycling.
