Monticello (/ˌmɒntɪˈtʃɛloʊ/ MON-tih-CHEL-oh) was the primary residence and plantation of Thomas Jefferson, a Founding Father, author of the Declaration of Independence, and the third president of the United States. Jefferson began designing Monticello after inheriting land from his father at the age of 14. Located just outside Charlottesville, Virginia, in the Piedmont region, the plantation was originally 5,000 acres (20 km), with Jefferson using the forced labor of enslaved black people for extensive cultivation of tobacco and mixed crops, later shifting from tobacco cultivation to wheat in response to changing markets. Due to its architectural and historic significance, the property has been designated a National Historic Landmark. In 1987, Monticello and the nearby University of Virginia, also designed by Jefferson, were together designated a UNESCO World Heritage Site. The United States nickel has featured a depiction of Monticello on its reverse every year since 1938 with the exception of 2004-05.
Jefferson designed the main house using neoclassical design principles pioneered 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 850 ft-high (260 m) 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 slaves 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 slaves who worked in the fields were farther from the mansion.
