This education center used to allow visitors to tour the three 18th- and early-19th-century homes on its property, but no more (there's a chance the 1730 Parsons House might reopen at some point). For now a small museum displays items such as cradles and carved chests from the 1700s, Calvin Coolidge memorabilia, and a dozen ornate silk dresses from 1835 to 1910.
