The Fascinating World of Time Capsules


The Massachusetts State House Time Capsule

The United States’ oldest known time capsule was the work of none other than Samuel Adams and Paul Revere. In late 2014, repairmen fixing a water leak at the Massachusetts State House uncovered a brass box that the two former Sons of Liberty had placed in a cornerstone to mark the building’s construction back in 1795.

When it was finally unsealed in 2015, however, the Massachusetts State House Time Capsule was found to contain a trove of preserved artifacts including newspapers, coins dating back to the 1600s, a page from the Massachusetts Colony Records and a copper medal with an image of “General of the American Army” George Washington. Most exciting of all was a silver plaque—believed to be engraved by Paul Revere himself.
