From Newburyport all the way to New Bedford, Massachusetts has many places steeped in a rich and interesting maritime past. Recently, the National Park Service's National Register of Historic Places and Maritime Heritage Program created this interactive guide to the maritime history of the Bay State. The site spares no punches, as it opens with a lovely photograph of the Boston Light Station on Little Brewster Island, complete with some very appropriate sound effects. Visitors can explore the sites through a series of interactive maps and then read four essays that deal with maritime commerce, shipbuilding, the U.S. Navy, and lighthouses and lifesaving stations. For each site, visitors can read a brief history and learn more about visiting each destination. It's a great way to learn about this particular part of the United States, and it could serve as the inspiration for a nice vacation as well.
