100-year-old courthouse time capsule recovered in Coeur d’Alene

A rusted copper box hidden in the old Kootenai County courthouse cornerstone finally came out on June 3, pulled from the wall at 501 Government Way after preservationists and masons spent hours opening the brick around it. The find turned a century-old rumor into a tangible link to the people who built Coeur d’Alene’s courthouse and chose what to leave behind for the next generation.

What began as courthouse lore had to be proven the old-fashioned way. County preservation leaders used digitized and microfilm newspaper archives to confirm the capsule existed and to narrow down where it had been placed. A fiber-optic camera then showed what appeared to be the corroded box behind the cornerstone before crews removed several layers of brick and lifted it out.

The container itself looked fragile and stubborn at once: a small copper box with heavy corrosion, no obvious seam and a hole that revealed crumbling paper inside. Britt Thurman of the Museum of North Idaho said the contents would be opened by the least invasive method possible, a cautious approach for an object that matters as much for what it represents as for what it holds.

Walter Burns of the Coeur d’Alene Historical Preservation Commission and Jonathan Mueller of the Kootenai County Historical Preservation Commission helped explain the retrieval, while Shannon Sardell inspected the cavity and Dobson Chimney and Masonry Services handled the brick removal. Theresa Alexander, one of the onlookers, said the moment was exciting for local history buffs. The scene blended construction dust, archival research and the kind of civic curiosity that only shows up when a county gets to touch its own past.

That past reaches well beyond the capsule. The courthouse was built in 1925-26, designed by Spokane architect Julius A. Zittle in the Georgian Revival style, and added to the National Register of Historic Places in 1977. County records show commissioners adopted Resolution 2025-97 on Dec. 23, 2025, recognizing a July 3, 2026 America250 celebration on the courthouse east lawn, where Idaho Supreme Court Justice Cynthia Meyer is scheduled to speak and local high school bands and musicians with the Coeur d’Alene Music Conservancy are expected to perform.

The timing gives the capsule a sharper meaning. Kootenai County is not just unsealing a relic; it is comparing the values of 1926 with the priorities of 2026, from courthouse preservation to civic celebration to the way residents tell their own story. The Coeur d’Alene Historic Preservation Commission is already running a children’s coloring contest for a new time capsule to be opened in 2126, setting up the next century’s version of the same question: what would Kootenai County choose to say about itself today?
