The traditional home of employees at the now-decommissioned Navy Yard, Charlestown has experienced a shift in its population and industry. The Navy Yard, a national historic landmark, has been converted to residential and office space, and an increasing number of young professionals are joining the families who have lived in the area for years. These newcomers are discovering Charlestown's renovated rowhouses and its accessibility to downtown Boston and the North End. Many residents walk to work in downtown or simply down to the nearby waterfront, both of which are only five minutes away.
