Walnut Grove, a historic home in Spartanburg County, South Carolina, traces its origins to the mid-18th century, when the property was granted to Charles and Mary Moore. Over the centuries, the house has borne witness to the region’s layered history — from the Revolutionary War through generations of agricultural, domestic, and community use.
A Revolutionary-Era Home with Deep Roots in the Carolina Backcountry
Historical accounts associated with Walnut Grove describe the site’s role during the American Revolution, when members of the Moore family supported the patriot cause. According to these accounts, a Moore daughter watched for approaching British troops and rode to warn nearby patriots — a story long tied to events leading up to the 1781 Battle of Cowpens. While details vary, the site remains closely associated with the Revolutionary era and the broader military campaign that unfolded across the South Carolina backcountry.
Evaluating a Structure Under Threat
More than 250 years after its construction, the house itself was showing the strain of time. Fire damage, water infiltration, and termite activity had compromised original wooden beams and foundation elements, and the second floor was no longer safe for use. In 2020, the Spartanburg County Foundation, which has owned the property since it was donated by Moore family descendants in the 1960s, initiated a comprehensive evaluation to determine how the structure could be stabilized and preserved for future generations.
The foundation enlisted McMillan Pazdan Smith Architecture, Bennett Preservation Engineering and Huss Construction to guide the work.
Stabilizing the Foundation While Preserving Historic Fabric
Structural repairs began at the foundation, where failing supports had caused the building to lean. Crews carefully lifted the house in small increments to install new masonry piers alongside original log elements, providing stability while preserving historic fabric. Inside the walls, engineers encountered unusual construction techniques, including stacked logs separated by wooden battens rather than bearing directly on one another. Over time, deterioration of these battens had weakened load paths, requiring targeted reinforcement.
Other challenges emerged as work progressed. Floors had sagged unevenly, and chimneys leaned subtly out of alignment. To address these conditions with precision, the team used three-dimensional laser scanning to document existing geometry, allowing new structural supports to be added without flattening or disguising the building’s historic irregularities. Where possible, original members were retained and strengthened through sistering rather than replacement.
Many times when we opened a wall, we found something we didn’t expect. The goal was to solve those problems without forcing the building to behave like a modern structure. We used technology to understand what we had, but the solutions still had to respect how the house was originally built.”

From the outset, the goal was not to recreate an idealized version of the past, but to retain as much original material as possible while addressing structural deficiencies that threatened the building’s long-term survival.
Restoration Guided by Evidence, Not Assumption
A historic photograph of Walnut Grove from 1904 became a critical reference point. It offered the clearest documented evidence of how the house appeared at a known moment in its evolution. Rather than speculating about earlier configurations, the project team used the image to inform exterior details and proportions, anchoring restoration decisions in verifiable evidence.
“With a building this old, the instinct can be to replace anything that looks compromised,” said Craig Bennett of Bennett Preservation. “Our approach was the opposite. We wanted to stabilize what was there and let the building’s original craftsmanship and imperfections remain visible.”
Archaeological Discoveries Expand the Historical Record
Stabilizing the structure also created opportunities for archaeological research across the property. As work progressed, local archaeologists identified remnants of what are believed to be two quarters associated with enslaved people who lived and worked at Walnut Grove. Measurements and layout closely align with known examples of such structures from the period, providing physical evidence that adds depth to long-standing historical records.
While it has long been understood that enslaved people labored at Walnut Grove, the archaeological findings have expanded how that history is interpreted and shared. The discoveries have helped inform ongoing research, descendant engagement and public education, reinforcing the site’s role as a place where multiple histories intersect.
Material Clues Reveal Everyday Life in the 18th and 19th Centuries
The restoration also revealed tangible traces of the home’s past. Craftspeople preserved evidence of early grain painting, a decorative technique used to make pine resemble more expensive wood, and documented original hardware, including door locks bearing British royal warrants. These elements now contribute to interpretation of the household’s material culture and social standing during the 18th and 19th centuries.

Walnut Grove is more than a historic house; it’s a place where generations of stories intersect. Preserving it ensures that people can continue to explore those stories, ask new questions and better understand the history of this community.”

An Ongoing Story of Stewardship and Shared History
While major construction is complete, Walnut Grove’s story remains unfinished. Community engagement and transparency guided the restoration process, helping ensure that the site reflects shared history rather than a single narrative. Today, Walnut Grove stands not only as a preserved Revolutionary-era home, but as an evolving educational resource shaped by evidence, stewardship and collective memory.
