Everyone knows that there are lots of interesting facts about Massachusetts. The state is home to some of the most important moments in our nation’s history. From the Boston Tea Party to the first-ever Dunkin’ Donuts, it’s easy to say that the Bay State is some of America’s most important treasures. However, when it comes to Massachusetts state facts, they are a few that aren’t as widely known. Massachusetts is the birthplace of some lesser-known gems and relics. From fun facts about Massachusetts to oddball Massachusetts trivia, here are some interesting facts about Massachusetts that we’ll bet you never knew…until now.

1. The first subway system was built in Boston.

The T is just a normal part of our lives here in Beantown, but Boston’s subway system was the first ever created. Since its construction in 1897, we all know it’s had quite a few hiccups, but it’s still been a main form of transportation in Beantown for more than a century. It's not just a mode of transportation, though. There are also a few surprises hiding underground in Massachusetts.

2. The Fig Newton? Yep, that was named after Newton, Massachusetts.

These beloved treats were invented in Cambridge in 1891. They were almost called "Fig Shrewsbury," but Newton won. In our opinion, Fig Newton sounds way better.

3. The first zip code ever is in Massachusetts. Shout out to 01001!

While the first zip code in the world is in Germany, the first of the states is in Agawam, Massachusetts.

4. Our official state cat is the Tabby cat.

In 1988, our state got its official state cat: the Tabby cat. This was in response to many schoolchildren’s wishes.

5. Also, our official state muffin is the corn muffin.

Children have a lot of power in Massachusetts since our state muffin was also decided by a petition created by schoolchildren back in 1986.

6. The first public park to ever exist was Boston Common.

Boston Common dates all the way back to 1634, when it became the first public green space. While this spot is now a popular attraction in Boston, another interesting fact is that it used to be used to graze sheep!

7. It’s technically illegal to use tomatoes in clam chowder in Massachusetts.

There are quite a few under-the-radar laws in Massachusetts from back in the day that aren’t enforced anymore. One prohibits using tomatoes in clam chowder since no classic New England recipe would ever allow for tainting Massachusetts’ most famous dish with tomato!

8. Once upon a time, Christmas was illegal in Massachusetts.

Way back in 1659, Boston passed a law that outlawed the celebration of Christmas. This was due to Puritans believing the holiday was too indulgent, and therefore immoral. Of course, this was reversed about 20 years later - and it's a good thing, too, because Christmas in Massachusetts is absolutely magical!

9. We have a state polka song. It’s called “Say Hello To Someone From Massachusetts.”

This song was written by Lenny Gomulka and officially became our state polka song in 1998.

10. In Webster, you’ll find Lake Char­gogg­a­gogg­man­chaugg­a­gogg­chau­bun­a­gung­a­maugg.

Nope, that’s not a typo. What’s now known to most as Lake Webster was originally Lake Char­gogg­a­gogg­man­chaugg­a­gogg­chau­bun­a­gung­a­maugg before being shortened to Lake Chaubunagungamaug. It derives from the Loup dialect, which is an Algonquian language. Not only is it the most unique lake in Massachusetts, but it's the longest place name in the country.

11. Retired rocking horses can be found at a spot called Ponyhenge in Lincoln, Massachusetts.

If you drive through Lincoln, you may come across one of the most unique roadside attractions in Massachusetts, a strange gathering of plastic rocking horses. These ponies mysteriously appeared sometime in 2010, and no one knows why. It started with just one horse, but it has grown over the years. Locals have officially named this anonymous roadside attraction "Ponyhenge."
