Old Hill Burying Ground is among Concord's earliest burial places, occupying elevated ground near the town center. Established in the seventeenth century, it preserves the graves of ministers, magistrates, craftspeople, farmers, women, children, and military participants from successive generations. Its stones form a documentary landscape of Puritan settlement, family networks, disease, mortality, religious belief, and the development of local stone-carving traditions.

Among those buried there is Colonel James Barrett, a Concord farmer and militia leader. In 1775, provincial authorities placed Barrett in charge of military stores accumulated in the town. Cannon, food, ammunition, and other supplies were dispersed among farms and hiding places to reduce the chance that British troops could seize them. Barrett's own farm became one of the objectives of the expedition sent from Boston on April 18.

On April 19, British regulars searched Barrett's property after fighting had begun at Lexington and Concord. Much material had already been moved or concealed, and the search yielded little. Barrett commanded militia at the North Bridge, where colonial companies confronted British troops and exchanged fire. His role joined preparation and combat: he helped organize supplies before the crisis and exercised authority when the confrontation became open war.

Barrett died on April 11, 1779, while the Revolution continued. His grave attracts attention because of 1775, but surrounding stones place him within the community that supported militia mobilization. Families produced food, wagons, intelligence, clothing, and labor, and they managed farms while men served. Enslaved and free Black residents were also part of Concord's population, though their graves and contributions are less consistently marked in older commemorative narratives.

Preservation of Old Hill requires mapping stones in their original relationships, documenting inscriptions, and using restrained conservation. Weathering, vegetation, ground movement, and past repairs threaten fragile slate and sandstone. Barrett's grave should be interpreted as one element of a much older cemetery rather than as the reason the ground exists. The site's value lies in combining a nationally important military association with the collective record of a New England town across nearly four centuries. Visitors should avoid rubbings, chalk, and direct contact with unstable stones. High-resolution photography and controlled lighting can recover inscriptions safely while creating a permanent record of carvings that weather will continue to soften. Town records and probate files can connect carved names with homes, occupations, and family property. Such research turns weathered stones into fuller biographies and helps visitors understand that the burying ground represents a community, not simply a roster of famous revolutionary men.
