"the baseball stadium"? Really? Don't you mean Fenway Pak?

Opened in 1912, IIRC.
Btw, y'all (I did grow in VA after all) guys are good. I lived there for 20 years and would have suggested many of these siights.
Lots of great places there for seafood, but if you want good seafood and a little history, try Woodman's in Essex. Inventor of the fried clam and been there for over 100 years. It's north of Boston a bit so you'll need to drive.
A visit to Harvahd (really Harvard) Sq. is always fun and for sure visit the North End (Boston's Little Italy) for dinner and then grab a pastry at Mike's or Cafe Vitorria. I might be off the last place's name, but it's close.
And if you visit HS, Kendsall Sq. is only a couple T stops away. This is where MIT is located. The subway in Boston is run by the MBTA and is called the T for short.
Visit Lexington (shot heard 'round the world that created our great country). It's maybe 15 miles outside Boston.
