Last week, the Globe ran a nice story on the history of the mile markers in Boston. Our neighborhood is fortunate enough to have two of these from the 1700's, the Parting Stone in Eliot Square and the 3-mile marker just down Centre across from Gardner. Most of these were installed by Paul Dudley, one of Roxbury's many famous Dudleys.
The story also included this map showing the location of all the mile markers around Boston. If you've never taken the time to stop and visit the Parting Stone or Mile Marker 3, make sure you do next time you're walking around the neighborhood!
