With a long-spanning history from war battles to coal barons, Mercer County is overgrown with WV’s roots, from museums that chronicle Civil War skirmishes to the lavish homes of the former coal barons. You can walk along the row of intricate mansions in Bramwell, once the town of the most millionaires per capita in the country, stopping for lunch in one of the old-fashioned diners for a home-cooked meal.
