A corroded copper box sealed inside the outer wall of the old Kootenai County courthouse in Coeur d’Alene was recovered this week, nearly a century after it was placed there during a dedication ceremony in April 1926. The retrieval marks the beginning of a community celebration planned for July 3 on the courthouse lawn, timed to coincide with both the nation’s 250th anniversary and the courthouse’s centennial.
A Rumor Confirmed After Decades
The effort to find and recover the capsule began as little more than local lore. Walter Burns, chair of the Coeur d’Alene Historical Preservation Commission, led the retrieval effort after years of uncertainty about whether the capsule actually existed. Jonathan Mueller, chair of the Kootenai County Historical Preservation Commission, spearheaded the research side of the project, working to confirm the capsule’s presence before any physical work began.
“It was a bit of a treasure hunt,” Burns said. “It started as a rumor. We really had nothing to back it up.”
To confirm the capsule’s location, Shannon Sardell — a historical architect and member of the city’s historic preservation commission — used a fiber-optic camera to probe inside the wall. The capsule was found behind a gray cornerstone bearing the names of county commissioners and the original dedication date, which had served as the only visible clue of what lay beneath.
Once the location was confirmed, Dobson Chimney and Masonry Services carefully removed bricks from the exterior wall to allow the capsule to be extracted without damage to the surrounding structure.
What Was Found Inside the Wall
The capsule itself is a small copper box showing significant corrosion after a century inside the building’s masonry. No obvious opening or seams were visible on the exterior, and a hole in the damaged box revealed crumbling paper inside. The contents are believed to consist primarily of documents, though their exact nature won’t be known until the public opening.
Britt Thurman, executive director of the Museum of North Idaho, took custody of the box after its removal. Thurman described the capsule as a direct communication from Coeur d’Alene residents of a century ago, saying it reflects what people in 1926 felt was worth preserving for the future — a window into who they were and what they valued.
Historical context adds significance to the find: when the cornerstone was originally dedicated in April 1926, roughly 1,500 people gathered for the ceremony in a town with an estimated population of just 7,000. That turnout — representing more than one in five residents at the time — suggests the courthouse held considerable civic importance for early North Idaho communities.
July 3 Opening Planned on Courthouse Lawn
The formal opening of the capsule is set for July 3, with a public celebration scheduled on the courthouse lawn in Coeur d’Alene. The event will serve a dual purpose: honoring the courthouse’s 100-year history while also participating in the broader national commemoration of America’s 250th anniversary.
As part of the July ceremony, organizers plan to dedicate and seal a new time capsule — one intended to be opened a full century from now, preserving a record of Kootenai County life in 2026 for future generations.
The Museum of North Idaho will hold the original capsule until the opening, at which point residents will learn exactly what Coeur d’Alene’s early 20th-century community chose to leave behind. For history enthusiasts in the Panhandle region, the July event represents a rare opportunity to witness a direct link between the county’s founding era and its present day.
What Comes Next
Residents interested in attending the July 3 celebration can expect the event to take place on the grounds of the old Kootenai County courthouse. The Museum of North Idaho is expected to provide additional context about the capsule’s contents once they are formally revealed. Community members curious about local preservation efforts or the history of Coeur d’Alene can also look into upcoming civic events — the city has recently highlighted other community-focused gatherings, including a Coeur d’Alene Arbor Day event offering free seedlings and tree planting activities as part of ongoing efforts to engage residents with the city’s heritage and natural environment.
