Jefferson designed the main house using neoclassical design principles described by Italian Renaissance architect Andrea Palladio and reworking the design through much of his presidency to include design elements popular in late 18th-century Europe and integrating numerous ideas of his own. Situated on the summit of an -high peak in the Southwest Mountains south of the Rivanna Gap, the name Monticello derives from Italian meaning little mountain. Along a prominent lane adjacent to the house, Mulberry Row, the plantation came to include numerous outbuildings for specialized functions, e.g., a nailery; quarters for enslaved Africans who worked in the home; gardens for flowers, produce, and Jefferson's experiments in plant breeding—along with tobacco fields and mixed crops. Cabins for enslaved Africans who worked in the fields were farther from the mansion, out of Jefferson's sight both literally and figuratively.
