For 25 years, a giant blueberry dome on Route 1 in Columbia Falls has been one of Maine's most beloved roadside stops. Now Wild Blueberry Land is up for sale, and Maine Preservation, the nonprofit that tracks the state's most threatened historic sites, has just added it to its 2026 Most Endangered Places list.

The building itself is in good shape. Maine Preservation reports the dome is structurally sound. The real risk is what happens after a sale. Owners Marie and Dell Emerson, longtime blueberry farmers, are ready to pass the property on, and nothing guarantees the next owner will keep it standing. "I don't want to see the building destroyed," Marie Emerson told Maine Public. "It has to be the right person."

This place matters far beyond one stretch of highway. Emerson estimates that 15,000 to 20,000 people visit every year. She describes kids cheering as they pull in and older visitors singing their way down the yellow brick road. Every visit also teaches people about wild blueberries, a crop tied to generations of Downeast farm families.

Landmarks like this don't come back once they're gone. The Columbia Falls Board of Selectmen, the Maine Historic Preservation Commission, and the Wild Blueberry Commission of Maine can help make sure this one survives. They can help connect the Emersons with preservation-minded buyers, explore protections such as a historic designation or preservation easement, and show that Maine stands behind this piece of its heritage.

Sign the petition to keep Wild Blueberry Land standing and open for families, while there's still time to find the right buyer.
