Grasse Mount (otherwise known as the Thaddeus Tuttle House) is a campus building of the University of Vermont (UVM), which is located on 411 Main Street (adjacent to the intersection of Summit Street) in Burlington, Vermont. Built in 1804 for Captain Thaddeus Tuttle (1758–1836), a local merchant, the building was designed by architect and surveyor John Johnson and constructed by carpenter Abram Stevens. By 1824, Tuttle had lost his fortune and sold the property to Vermont Governor Cornelius Van Ness. Named after French Admiral François Joseph Paul de Grasse "Grasse Mount" was added to the National Register of Historic Places on April 11, 1973.
