Little Garden has a detail that no one in the story explains: why are two Viking giants from Elbaf on a remote prehistoric island, fighting a duel that has lasted over 100 years? The answer is not in the manga. It is in the history books.
The Previous Theory Was Wrong
The widely circulated theory placed Little Garden at Yellowstone National Park in the American West — based on the geysers and dinosaur fossils. Yellowstone is right about the geological features. But it misses the decisive piece of evidence: the building where Dorry and Broggy live.
The Real Model: L’Anse aux Meadows, Newfoundland
Dorry and Broggy make their home inside a dinosaur skull — a long, elongated structure with a rough-hewn, ancient quality. The model for this building is the longhouse at L’Anse aux Meadows in Newfoundland, Canada — a UNESCO World Heritage Site.
L’Anse aux Meadows is the only confirmed Viking settlement ever found in North America. The longhouse — the signature dwelling structure of Norse culture, a long narrow communal building — is the architectural centerpiece of the site. The elongated shape, the ancient materials, the remote coastal location: this is Dorry and Broggy’s home.
Once the UNESCO World Heritage building is identified, the country is confirmed. Little Garden is Canada.
Why Vikings Are There: The Real History
Around 1000 CE, Norse explorers sailed west from Scandinavia — through Iceland, through Greenland — and reached the coast of North America. Leif Erikson is the most documented of these expeditions. They arrived in Newfoundland approximately 500 years before Columbus.
This is the answer to the unexplained story question. “Why are two giants from Elbaf — a Viking-inspired nation — on a remote island far from their homeland?” Because in real history, Vikings actually sailed to a remote island far from their homeland and built a settlement there. The historical fact that Vikings reached Canada is the in-world reason why Viking giants are on Little Garden.
Oda does not explain this in the text. He does not need to. The answer is in the model, available to anyone who identifies the location.
The Dinosaurs: Dinosaur Provincial Park, Alberta
The dinosaur fossils scattered across Little Garden point to a second Canadian location: Dinosaur Provincial Park in Alberta, also a UNESCO World Heritage Site. Alberta’s badlands contain one of the world’s richest concentrations of Late Cretaceous dinosaur fossils — the largest dinosaur bone beds on Earth. The prehistoric atmosphere of Little Garden draws from both sites: L’Anse aux Meadows for the Viking presence, Dinosaur Provincial Park for the fossil landscape.
The Geyser: Old Faithful
The massive geyser on Little Garden is modeled on Old Faithful at Yellowstone — the world’s most famous geyser, which erupts on a roughly 90-minute cycle. Yellowstone is a UNESCO World Heritage Site. It contributes the geological spectacle. But Yellowstone is in the United States, not Canada, and the building — L’Anse aux Meadows — is the decisive evidence for the island’s actual model country.
Little Garden is a composite of three UNESCO World Heritage Sites, all in North America, each contributing a different element. The Vikings are Canadian. The fossils are Canadian. The geyser is American. And the reason Vikings are on a prehistoric island in the first place is that real Vikings actually went to prehistoric North America.
