Louisa County, in the heart of the Virginia Piedmont, was named for Louisa, a daughter of George II, and was formed from Hanover County in 1742, with Louisa as its county seat. Its historic resources include the Green Springs Historic District, including Boswell’s Tavern, which was used on one occasion during the Revolution as headquarters of the Marquis de Lafayette, as well as the monumental Louisa County courthouse and the old jail. Fluvanna County takes its name from an 18th-century term for the upper James River, meaning river of Anne, originally bestowed in honor of England’s Queen Anne. Formed from Albemarle County in 1777, it includes notable architectural and historic resources in the Bremo Historic District—Upper Bremo, Lower Bremo, and Recess—and in the Fluvanna County Courthouse Historic District, where at the county seat of Palmyra a temple-form courthouse designed by Gen. John Hartwell Cocke dominates a small cluster of court structures.
