Overview
- City of Boston archaeologists led by Joe Bagley located a defensive ditch that matches Henry Pelham’s square redoubt during excavations shown to the public on the June 17, 2026 anniversary.
- Ground‑penetrating radar guided targeted trenching that revealed the ditch and structural features described on Pelham’s 1775 map.
- Excavators have recovered musket balls, musket parts and British‑associated items such as tea cups, pipes, sleeve buttons and a wig curler, with specialists saying some musket balls show markings consistent with having been fired.
- No human remains have been found so far, and a forensic archaeologist is on site to identify any bones if they appear during the ongoing dig.
- The fieldwork has coincided with a court order that kept three National Park Service interpretive quotes on display, highlighting how new finds and legal fights are shaping public memory and future study of the site.
