Burying a time capsule is like sending a message to the future. It’s a snapshot of life meant to outlast its makers. Over the years, many of these capsules have been unearthed, revealing surprising, heartfelt, and sometimes humorous glimpses into the past.
Here are ten of the most fascinating time capsules ever opened, along with the treasures they contained.
The 1876 Century Safe: A Victorian Peek Into the Future
Sealed at the 1876 Philadelphia Centennial Exhibition, the “Century Safe” was America’s first official time capsule. When it was opened 100 years later in 1976, it revealed letters from President Grant, a sewing machine, and a temperance pamphlet. It serves as a sober reminder of 19th-century values.

Samuel Adams and Paul Revere’s Capsule (1795)
Hidden beneath the Massachusetts State House cornerstone, this capsule was discovered in 2014. Inside were colonial coins, newspapers, and a silver plate engraved by Paul Revere. It was reburied with modern items added—a dialogue between past and present patriots.
The Crypt of Civilization (1936)
Buried at Oglethorpe University in Georgia and sealed until the year 8113, this massive vault was briefly opened for inspection. It contains thousands of artifacts, including a typewriter, dental floss, a Donald Duck toy, and microfilm of books. It’s a time capsule so ambitious it’s often called “the first planned archive of modern civilization.”
Tulsa’s Buried Belvedere (1957)
To celebrate Oklahoma’s 50th anniversary, residents buried a brand-new Plymouth Belvedere car, expecting it to be pristine when opened in 2007. Unfortunately, water leaked into the vault. The car emerged rusted and ruined, but the story became a local legend—a reminder that the future isn’t always kind to our best intentions.

Westinghouse Time Capsule (1939)
Created for the New York World’s Fair, this Westinghouse Time capsule was designed to last 5,000 years. A twin capsule was buried in 1965 for comparison. The 1939 version, briefly examined decades later, contained microfilm of Albert Einstein’s writings, seeds, and even a slide rule. It’s a treasure chest of 20th-century innovation.
The Nickel Time Capsule (1968)
Nickel, the Canadian mining giant, buried a capsule filled with coins, photos, and messages in Sudbury, Ontario. When it was opened 25 years later, it revealed perfectly preserved items and a prediction that humans would be living on Mars by the year 2000. Optimistic, but not quite accurate.
The Keio University Capsule (1960)
Buried in Japan and opened in 2010, this capsule contained a remarkable mix of cultural items: photographs, newspapers, and even children’s toys. The most touching inclusion was a collection of handwritten letters from students to future generations. It’s a gentle reminder that some messages never age.
