From The Boston Courant:
The location of a time capsule buried at a Back Bay mansion is a mystery.
Board members of the Boston Center for Adult Education (BCAE) buried the 3-by-4-foot glass capsule at its former Commonwealth Ave location…
When the center changed headquarters to 122 Arlington, they tried to take the slice of time with them, but digging in the area where it was supposed to be turned up nothing.
The orginal Back Bay (BCAE) building is now being renovated by the new owners and they declined to comment on about whether construction crews are keeping a look out for the capsule.
