The Milestones have been documented numerous times throughout the history of the United States, being included in the 1941 report by the Works Progress Administration and the 1960 preservations efforts of the Massachusetts Legislature Public Works Act. While there were once ninety-nine stones, not all stones have been located or preserved. However, as of the creation of the National Register of Historic Places nomination in 1971, at least forty milestones had been located, photographed, and preserved (either by creating a monument on-site or by the relocation of the stone.)
One of the most iconic of the milestones is known as the Wait Guide Stone. This stone bears an engraving which reads:
“This stone is erected by John Wait, Esq. of Brookfield for the benefit of travel here.”
Additionally, the stone is marked with the year 1763, making it one of the earliest stones to predate the official milestone project. The milestones themselves serve as visitor destinations in their own right, but they also add context to the historically rich region of Massachusetts within which they rest.
