In the quest to preserve America’s historic landmarks, the National Trust for Historic Places (NTHP) annually highlights sites in need of revitalization.
With a mission focused on educating the public about these treasures, the NTHP aims to boost visibility and attract resources necessary for the preservation of historic places.
Among the focal points in their 2025 report is a list showcasing 11 endangered locations across the United States.
Today, we will highlight five of these noteworthy sites that travelers may encounter during their adventures.
The Turtle in Niagara Falls, New York, stands out as an architectural tribute to Native American culture.
Constructed in 1981, this unique building was designed to resemble a turtle, reflecting the Haudenosaunee creation myth of Turtle Island.
Unfortunately, after the Native American Center for the Living Arts faced bankruptcy in 1996, the building was sold and repainted, obscuring its turtle-like features.
Plans are underway by the new owners to demolish The Turtle for a high-rise hotel, though a coalition of over 1,000 supporters, known as Friends of the Niagara Turtle, is advocating for its preservation and revitalization.
Another site of concern is Cedar Key, Florida, which embraces an ‘Old Florida’ charm that many visitors adore.
However, the community has faced significant challenges due to hurricanes such as Helene in 2024 and Hermine in 2016 that caused extensive damage, including the loss of historic wooden homes.
Ongoing threats from rising sea levels jeopardize not only infrastructure but also culturally significant sites linked to the indigenous Timucua peoples.
Fortunately, the Florida Trust for Historic Preservation, along with the University of Florida, is collaborating with Cedar Key to implement strategies to adapt and protect this picturesque locale.
In Los Angeles, California, the Terminal Island Japanese American Tuna Street Buildings exemplify a poignant chapter in American history.
The remaining structures—Nanka Shoten and A. Nakamura Co.—are remnants of a once-thriving community of Japanese workers.
This community was shattered during World War II, leading to internment and the destruction of many homes.
With the island now serving as a bustling storage port, there are plans to demolish these historical buildings, but local groups like the Los Angeles Conservancy and the Terminal Islanders Association are actively rallying against this.
Flagstaff, Arizona, is home to the May Hicks Curtis House, an emblem of local heritage that tells a story of community connection.
May Hicks Curtis, a prominent figure in the early 1900s, operated guesthouses for travelers on the original Route 66 and played an essential role in preserving local history through photographs and documentation.
Currently, the home faces an uncertain future following its sale for development.
Although the City of Flagstaff owns the property temporarily, the long-term prospects for the building remain in jeopardy.
In Phoenix, Arizona, the Mystery Castle attracts attention with its intriguing backstory.
Built between 1934 and 1945 by a devoted father for his daughter, this whimsical castle boasts 18 rooms and stands rather uniquely due to its unconventional design.
However, following the death of Mary Lou, the property transferred to a trust that has struggled to secure funding for its upkeep.
Ongoing vandalism has taken a toll on the castle, further complicating efforts to restore and stabilize this beloved landmark for public enjoyment.
Thankfully, initiatives led by groups like Preserve Phoenix and ‘Friends of Mystery Castle,’ in conjunction with the Phoenix Historic Preservation Office, are seeking the necessary support to save this one-of-a-kind site.
These highlighted locations are among many that contribute to America’s rich tapestry of history and culture, each facing distinctive challenges.
Through collaborative efforts and public engagement, it is possible to revitalize these endangered landmarks, ensuring they remain cherished components of community identity for generations to come.
For anyone interested in cultural preservation, this list serves as a vital reminder of our shared heritage and the importance of safeguarding it against the pressures of modern development and environmental change.
As we embark on our adventures, let’s not only appreciate these historic places but also recognize the importance of their preservation for future generations.
