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 United Colonies and the British Empire 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.
