16. Locust Grove
Locust Grove’s most famous resident was Samuel F. B. Morse, the inventor of the telegraph. Its name derives from the locust trees planted by Henry Livingston Jr., the estate’s first resident. Alexander Jackson Davis designed the Italianate style mansion for Morse in 1851. Almost no furnishings remain from when Morse lived at the house, though there is an informative exhibit on the inventor and a collection of some of his paintings in a visitor center.
