The Ernest and Mary Hemingway House, in Ketchum, Idaho, is listed on the National Register of Historic Places in 2015. The National Register does not disclose its location but rather lists it as "Address restricted." The property is the last undeveloped property of its size within the city limits of Ketchum.

The house was built 71 years ago in 1953 for Henry J. "Bob" Topping Jr. It is a two-story, 2,500-square-foot (230 m) home in Ketchum, west of the Big Wood River. Similar to the Sun Valley Lodge a few miles away, its exterior walls are concrete, poured into rough-sawn forms and then acid-stained to simulate wood. It was sold to Hemingway in 1959 for its asking price of $50,000, and the Hemingways occupied it in November 1959.

On the morning of Sunday, July 2, 1961, Hemingway died in the home of a self-inflicted head wound from a shotgun. After a brief funeral four days later, he was buried at the city cemetery.

The Nature Conservancy acquired ownership in 1986. In May 2017, ownership was transferred to The Community Library in Ketchum, a privately funded public library.

According to the Jeanne Rodger Lane Center for Regional History department of The Community Library, Ernest Hemingway's final home, and Mary Hemingway's home until 1986, is managed by The Community Library Association as a private residence for a Writer-In-Residence program, and the site of ongoing preservation efforts.

The Community Library became the custodian of the Hemingway House and Preserve in May 2017, following the 30-year ownership of the House by The Nature Conservancy. The change marked a new approach to the preservation and promotion of the iconic writer's legacy in the American West, and by a library whose own history is intertwined with Hemingway's.

The Community Library honors the House as a contemplative, non-commercial space, and they are prioritizing ongoing preservation efforts and a writer-in-residence program there.

The Ketchum, Idaho, house, and its associated 13.9 acres of land alongside the Big Wood River, is listed on the National Register of Historic Places for its association with the writer and because it is an exquisite example of mid-century architecture.

The house is incorporated into a larger historical and literary program that explores Hemingway's abiding connections to the remote and rugged region, a place he visited for two decades, and the place where he turned to make his final home after his departure from Cuba.

Artifacts from the Ernest and Mary Hemingway House and Preserve are being preserved by the Jeanne Rodger Lane Center for Regional History and will be made accessible to the public through periodic displays at the Library and the Wood River Museum of History and Culture, as well as through research requests.

Since taking over the management of the house and legacy, the Library undertook a needed series of restoration measures on the exterior and interior in order to protect the 1953 house and its contents. Notable in the infrastructure work done to date are the re-shingling of the roof — from shake back to shingle (with a Class A assembly); the painting of the house exterior trim; partially regrading the original gravel drive; installing a new boiler, and removing several dying trees.

Importantly, the preservation measure of replacing eleven picture windows in the living room, bedrooms, and kitchen with UV-protected double-paned glass will ensure the artifacts within the house against UV light damage. This project was made possible by a grant award from the Idaho Heritage Trust. We are pleased and thankful to be able to protect the house collections from the beautiful but harmful rays of sunlight that come through the windows.

"The Writer-in-Residence is a residency program based in Ketchum, Idaho, and managed by The Community Library, custodian of the historic and privately-operated Ernest and Mary Hemingway House and Preserve." The house is private. "The residency program is by invitation only, as we are focused at this time on aligning the residency with the Library's programs, major initiatives, and community partnerships.

This exhibit at the Wood River Museum of History and Culture in Ketchum, Idaho, examines who Hemingway was when he arrived in 1939: a writer at his peak, a globetrotter drawn to remote places, a rugged outdoor enthusiast, and a man with complicated personal relationships. Visitors can type their own “One True Sentence” on a vintage typewriter just like Ernest Hemingway used!
