Grasse Mount, Georgian architecture building in Burlington, Vermont, US

Grasse Mount is a Georgian-style mansion at 411 Main Street in Burlington, Vermont, built in 1804 for Captain Thaddeus Tuttle to designs by architect and surveyor John Johnson and erected by carpenter Abram Stevens. Captain Charles B. Marvin, who bought it in 1853, added an Italianate belvedere cupola on the roof, gas lighting, larger-paned sash windows and Italian marble fireplace mantels.

Built in 1804 for merchant Captain Thaddeus Tuttle, Grasse Mount was sold in 1824 to Governor Cornelius Van Ness after Tuttle's business failed. Van Ness, who later served as U.S. Ambassador to Spain, owned it until 1845. In 1825 the Marquis de Lafayette was entertained here after laying the cornerstone of the University of Vermont's South College.

The building displays wall paintings and stencil patterns from the 19th century that were discovered in 1984, reflecting different architectural periods. These preserved interior decorations offer a window into the artistic tastes of earlier residents.

The property is located at 411 Main Street and is now used by the University of Vermont Alumni Association. Visitors can view the exterior of the building, which sits along a busy downtown street.

The property's name honors French Admiral Francois Joseph Paul de Grasse, connecting this Vermont location to American naval history. This link to 18th-century French sailors makes the building a reminder of transatlantic ties.
