Farmington, an 18-acre (7.3 ha) historic site in Louisville, Kentucky, was once the center of a hemp plantation owned by John and Lucy Speed.

The 14-room, Federal-style brick plantation house was possibly based on a design by Thomas Jefferson and has several Jeffersonian architectural features.

Built in the Federal architectural style, the house is based on plans by Thomas Jefferson, which are now in the Coolidge Collection at the Massachusetts Historical Society.

It was during this visit to Farmington in 1841 that Abraham Lincoln witnessed slavery on a plantation first-hand and he saw enslaved people chained together after he boarded a steamboat at the Louisville waterfront.

The only substantial change in its interior or exterior appearance since construction was the installation of a tin roof in place of the original wood shingles, which was done for fire safety reasons.

In 2012, Farmington's owner, Historic Homes Foundation, Inc., entered into an agreement to sell 5 of the landmark's 18 acres to an adjoining landowner, Sullivan University, for use as a 300-space parking lot to be shared by both entities.
