The archaeological remains associated with the Farmington slave house consisted of a stone foundation, a large hearth, postholes, a drip line, and a sub-floor storage pit/cellar within the structure. Based on the exposed remains of the structure, investigators determined that it was a small building (16 x 16 feet in size) that had a porch. Based on the recovered nails and window glass, and a large amount of plaster, the slave house was a wood frame structure with plaster walls, a wood shake roof, wood plank floor, and glazed windows.
Ceramics recovered from the site indicated that the Speeds passed down a variety of dishes, including some expensive types, to the enslaved.
Other artifacts, such as a blue glass bead and a silver Mexican coin scratched with an “X” mark, likely held symbolic meaning for the enslaved people who lived at Farmington. Those objects were often stored in below-ground storage pits/cellars and kept out of sight of the plantation's overseers. The recovery of similar objects from other plantation sites in Louisville and elsewhere in Kentucky suggested that those enslaved at Farmington were part of a broader community of enslaved people.
