Hillsboro, also spelled Hillsborough, is a colonial plantation house in King and Queen County. The property stands several miles from the marker amid a rural landscape shaped by Indigenous occupation, English land grants, tobacco agriculture, and slavery. Tradition long dated the house to about 1722 and attributed it to Colonel Humphrey Hill; architectural study places its development within the eighteenth-century Hill family's ownership. Its brick ends and timber-framed front and rear make it an unusual regional survival.

The Hill family belonged to the county's landed society, whose wealth and political influence rested on agriculture and the labor of enslaved African Americans. A plantation house was the center of a working complex rather than an isolated residence. Fields, kitchens, quarters, barns, storehouses, and roads connected household life to export markets along Virginia's rivers. Surviving descriptions often celebrate the main house while leaving the names and experiences of the enslaved majority difficult to recover.

During the Revolutionary War, Virginia plantations supplied food, horses, taxes, militia, and accommodations. In 1781 the war moved forcefully into the Tidewater. British expeditions under Benedict Arnold, William Phillips, and later Lord Cornwallis used rivers and roads to destroy military stores and disrupt Virginia's capacity to support the Continental cause. Raiding parties also seized provisions and animals from private properties. The marker records that British troops raided Hillsboro, although it does not provide a date or detailed account.

A raid could involve the taking of livestock, food, weapons, valuables, or transportation, and it placed enslaved people in especially complex circumstances. British proclamations and military presence offered some a path away from enslavement, while others were forced to move with armies or suffered new losses. Without a full incident record, it is important not to invent particulars at Hillsboro. The documented fact of a raid nevertheless situates the plantation within the material demands and social upheaval of the Virginia campaign.

The house remained in Hill family hands and preserves significant early interior woodwork, including a Georgian stair. Some exceptional paneling was removed in the twentieth century and installed at Mount Cuba in Delaware, a reminder that historic interiors can be dispersed even when buildings survive. The property was listed in the Virginia Landmarks Register and National Register of Historic Places, recognizing its architectural importance and long association with the family.

Because Hillsboro is distant from the roadside sign, the marker asks travelers to imagine a broader historic landscape. Its brief text joins architecture and military memory but leaves much for interpretation. The site represents an elite dwelling, an enslaved labor system, a wartime target, and a rare surviving building. Reading all those elements together avoids reducing Hillsboro either to picturesque design or to an undocumented battle story, while preserving the genuine significance of a home touched by Revolutionary raiding.
