Solomon Willard was a carver and builder in Massachusetts who is remembered primarily for designing and overseeing the Bunker Hill Monument, the first monumental obelisk erected in the United States.

The Bunker Hill Monument is a monument erected at the site of the Battle of Bunker Hill in Boston, Massachusetts, which was among the first major battles between the Red Coats and Patriots in the American Revolutionary War. The 221-foot granite obelisk was erected between 1825 and 1843 in Charlestown, Massachusetts, with granite from nearby Quincy conveyed to the site via the purpose-built Granite Railway, followed by a trip by barge. There are 294 steps to the top.
