Nestled in forests around the world, a gentle army of giant wooden trolls want to show humans how to live better without destroying the planet.
The Danish recycle artist Thomas Dambo and his team have created 170 troll sculptures from discarded materials such as wooden pallets, old furniture and wine barrels.
Twelve years after he started the Trail of a Thousand Trolls project, his sculptures can be found in more than 20 countries and 21 U.S. states. Each year Dambo and his team make about 25 new trolls, which stand up to 40 feet (12 meters) tall.
“I believe that we can make anything out of anything,” said Dambo, speaking from his farm outside Copenhagen. “We are drowning in trash. But we also know that one man’s trash is another man’s treasure.”
An installation of six sculptures called Trolls Save the Humans is on display at Filoli, a historic estate with 650 acres of forests and gardens in Woodside, until November 10.
“They bring us back to be connected to the earth and to nature,” said Jeannette Weederman, who was visiting Filoli with her son in July.
Dambo’s trolls each have their own personality and story. At Filoli, the troll Ibbi Pip builds birdhouses, Rosa Sunfinger plants flowers and Kamma Can makes jewelry from people’s garbage.
“Each of them has a story to tell,” said Filoli CEO Kara Newport. “It inspires people to think of their own stories, what kind of creatures might live in their woods and make that connection to living beings in nature.”
Dambo’s trolls don’t like humans because they waste nature’s resources and pollute the planet. The mythical creatures have a long-term perspective because they live for thousands of years and have witnessed the destructive force of human civilizations.
But the six young trolls at Filoli have a more optimistic view of human nature. They believe they can teach people how to protect the environment.
“They want to save the humans. So they do this by teaching them how to be better humans — be humans that don’t destroy nature,” said Dambo, 45, a poet and former hip-hop artist. “They hope to save them from being eaten by the older trolls.”
Dambo’s trolls are hidden in forests, mountains, jungles and grasslands throughout Europe and North America as well as countries such as Australia, Chile and South Korea. Most were built with local materials and assembled on-site by his team of craftsmen and artists with help from local volunteers.
“My exhibition now has four and a half million visitors a year globally, and it’s all made out of trash together with volunteers,” said Dambo. “That is such a huge proof of concept of why we should not throw things out, but why we should recycle it.”
Thomas Dambo’s ‘Trolls Save the Humans’ is on display at Filoli (86 Cañada Rd, Woodside) now through Nov. 10, 2025.
