Correction: it’s THE roadside attraction, the oldest and still the best.
Especially as there are better Baha’i temples, like the coolest building in my home province:
That’s the Shrine of the Bab, in Haifa, Israel.
There’s also the Lotus Temple in New Delhi (also a Baha’i temple).
Obviously not in any of the United States.
Agreed. she’s amazing and just went through a good rehab.
I went there when I visited Israel. Yes, that is incredibly cool.
(I’ve also been to the Baha’i temple in Illinois.)
The coolest building in Maryland imho is Orioles Park at Camden Yards

Some nitpickers might object that a baseball stadium is not, in fact, a building, in which case I offer the Observation Tower in Patterson Park, Baltimore

But those nitpickers would presumably not include the folks who made the page we’re discussing, given that they included a racetrack.
My boring, absolutely cliche answer is the Space Needle.
But if you actually go up in it, it really is pretty cool.
I’m not posting a picture of it because I’m sure everyone knows what it looks like.
Personally I’m partial to the West Side Market:
If you like Frank Gehry buildings, there’s also the Peter B. Lewis Building at Case Western:
Do interiors count? Because I’ve always loved the inside of the Cleveland Arcade. The exterior isn’t particularly distinctive, though.

As for the state I currently l live in, I’m surprised they didn’t pick Biltmore:
The governor’s house is real nice and all, but Biltmore is pretty much over the top when it comes to nice houses.
Duke Chapel is pretty cool too:
And the Grove Park Inn:
I, on the other hand, never went there when it was an arena but have been there three times since it was remade into a Bass Pro Shop. It’s really impressive.
Nassau Hall is very nice. But it’s not as cool as Lucy the Elephant. (Which gets bonus points for being in the middle of a residential neighborhood.)
The Cliff Palace in Colorado? No, Bishop Castle. Never underestimate a loony that refuses to adhere to building or safety codes.
Landsleit! I was born in Atlantic City, and I adored Lucy too.
