Colorado’s most endangered sites in 2025 include a filming location for “Indiana Jones and the Last Crusade,” a 19th-century town hall, and an opera house that’s seen more uses than a Swiss Army knife.

This year’s quartet of buildings on Colorado’s Most Endangered Places list was announced Thursday as part of the Saving Places Conference at Cheyenne Mountain Resort in Colorado Springs. The program has for 28 years partnered with preservationists and citizens to try to save significant Colorado historic structures and culture.

That includes not only physical landmarks but also “intangible cultural elements like language, storytelling, music, and other community practices that embody our past and connect us to our future,” wrote Katie Peterson, director of the Endangered Places program, in the report.

The statewide program looks at both iconic buildings and family-owned businesses, rural or mountainous, and in the past has highlighted 144 “historic resources throughout Colorado.” That includes 57 successful saves, she wrote.

Colorado’s Most Endangered Places is the signature program of the nonprofit Colorado Preservation Inc., which was founded in 1984 and works to route preservation money to vulnerable buildings and cultures. The four new additions to the list are:

Indiana Jones Bed & Breakfast

This modest home near the New Mexico border in Conejos County is an important part of Colorado’s movie culture, preservationists said, but its history stretches back to 1888, when it was one of the first houses constructed in the San Luis Valley town of Antonito.

One hundred years after it was built by the Carroll family — who sold horses and mules to miners — it became the boyhood home of Indiana Jones in 1989’s “Indiana Jones and the Last Crusade.” “The opening scenes … were filmed there, with the action centered on the historic Cumbres & Toltec Railroad and the charming Victorian building at 502 Front Street, now known as the Indiana Jones Bed & Breakfast,” according to Colorado Preservation Inc. (CPI).

The current owners run it as a bed and breakfast, but the adobe home is beginning to sag and shift and needs a new foundation before any other work can be done, CPI said.

Knearl Block and Opera House

This red-brick building in Brush has served as a post office, hat-making factory, hotel, restaurant, opera house, bank, bar and telephone exchange — and since 2003 has been the Corral Sports Bar & Grill. Eastern Colorado communities rely on these multi-faceted structures as civic hubs, CPI said, and the architecture of the 1902 building “reflects the grandeur of its era.”

“With its intricate brickwork, tall windows, and timeless facade, the building captures the elegance of early 1900s design,” CPI wrote. “The owner has taken as many steps as possible to stabilize the building using available funds. Unfortunately, time has taken its toll on the building, rendering the upper story unusable and the south wall beginning to detach.” And that’s despite the Morgan County structure joining the State Register of Historic Places, CPI added.

Newman Block

This modest blue building once housed the Granada Fish Market, which was owned by Frank Masa Tsuchiya, who had been incarcerated at the Japanese-interment site Camp Amache near Granada, CPI said. He founded the business in 1943 after his release from the World War II-era camp.

“He worked alongside Frank Torizawa, who had also worked in a fish market before the war,” CPI wrote. “Together, they delivered fish, poultry, and ice to those still incarcerated at Amache (and) donated various items to improve the lives of those behind barbed wire.”

It’s currently vacant and used as a rental event space, but “attention was drawn to the structures when one of the four buildings that share walls collapsed,” CPI wrote. They hope to work with the private owners, the Amache Alliance, the Amache Preservation Society, and the National Park Service to shore it up and explore future uses, CPI said.

Red Cliff Town Hall

This Main Street structure in the Eagle County town of Red Cliff — itself inside the White River National Forest — is a historic town Hall and firehouse that stands as an “enduring (symbol) of the town’s rich heritage and (is) central to its community life,” CPI wrote.

Built in around 1887, it was a key site for the Battle Mountain Mining District. “But after fires in 1882 and 1883 destroyed most of the town, residents realized the need for a better system to help fight fires,” CPI said. The town added water pipes and hydrants that drew from nearby Willow Creek, and eventually the building was used as a dance hall, a jail (added to the rear in 1927) and a day care before its 1980 closure.

“Unfortunately, the building is in failing condition and not structurally sound,” CPI wrote. “Rotting wood and a sloping foundation contribute to the building’s decline.” Boosters hope to turn it into a museum.
