In 2021, a strange lead box was discovered at the base of a monument to Thaddeus Kościuszko, a Polish military leader who fought in the Revolutionary War, at the U.S. military's West Point academy. Officials determined it was placed there in 1828.

Calling it a "unique discovery" and "another example of past generations of cadets gripping hands with present and future generations," the academy planned a dramatic opening ceremony that featured a panel of military personnel and experts. The event was live-streamed on Monday, and began by hyping up the possibilities of what could be inside the box.
