The home was built about 1680 and Revere owned it from 1770–1800. Much of its notoriety comes merely from its survival. It’s one of the few (the only?) house from the 1600s still standing in Boston.
By adding in the legend of Paul Revere, it elevate the house’s status. I think most of the fame of Paul Revere comes the famous Wadsworth poem “The Midnight Ride of Paul Revere.” The poet focused on Revere, but ignored the William Dawes, who had been sent on the same errand by a different route.
