Declared one of America's most at-risk historic places in 2024 by the National Trust for Historic Preservation, New York's Hudson-Athens Lighthouse is a local landmark in peril. For more than 150 years, the structure has provided safe passage for boats traversing the Hudson River, as well as offering a unique home to lighthouse keepers and their families through the decades.

In the mid-19th century, the Hudson River was growing into an increasingly busy and hazardous shipping route. Consequently, Congress provided $35,000 in 1872 to fund the construction of a lighthouse. In modern money, that translates to around $902,300 (£689k) today. Work on the facility began in 1873 and the lighthouse was operational by November of the following year.
