About Rollstone Boulder
Fitchburg’s Rollstone Boulder is a natural glacial erratic with an extremely unnatural second act. The enormous rock once sat on Rollstone Hill, where quarrying gradually threatened the local landmark. Rather than accept its destruction, the city decided to move a boulder weighing roughly 110 tons.
There was one obvious problem: moving a rock that size intact was not practical. The solution was wonderfully contradictory. The boulder was documented, marked, broken into transportable pieces, and hauled down from the hill. Local preservationists destroyed the thing in order to save it.
The fragments were reassembled beside Fitchburg’s Upper Common in 1929 and 1930. The seams remain visible, so the finished object is both one ancient glacial boulder and a giant human-made reconstruction of that same boulder. The Fitchburg Historical Society still preserves photographs of the separated pieces from the move.
Today Rollstone Boulder sits in a small public area near the Upper Common, where no mountain hike is required to see it. The city lists the park at 857 Main Street and keeps the Common open from dawn to dusk. It is hard to imagine a more committed form of local affection than blowing up a beloved rock, numbering the chunks, and putting the whole thing back together downtown.
