Salem was once one of America’s busiest and most prosperous ports. The Derby Wharf at Salem was built over a 44-year time span and eventually reached a length of half a mile. It served Elias Derby’s fleet of local and international trading vessels, which made him one of America’s first millionaires. Privateers operated out of this port during the War of 1812. A replica of the privateer ship Friendship is open for tours at the Salem Maritime National Historic Site. Take Route 128 to Salem, then Route 114, onto Derby Street.
