Adams National Historic Park

The Adams family sights are accessible by guided tours, which depart from the Adams National Historic Park Visitor Center. Every half-hour, trolleys travel to the John Adams and John Quincy Adams Birthplaces, the oldest presidential birthplaces in the United States. These two 17th-century saltbox houses stand side by side along the old Coast Rd, which connected Plymouth to Boston. The houses are furnished as they would have been in the 18th century, so visitors can see where John Adams started his law career, started his family, and wrote the Massachusetts Constitution (which was later used as the basis for the US Constitution).
