Comparatively few historical ruins built out of materials that would have lasted this long, but a long history, actually, and some you can still see...

Mexico City is a quick plane ride from the USA, and while some of their ruins are buried, you can hop a short bus ride outside the city to walk among standing ruins of Teotihuacan, the largest city in the Western Hemisphere at the time Jesus walked on the Earth. It was 20 square kilometers whereas Rome at the height of the empire had only 14 square kilometers within the Aurelian Walls.

I've been on the Great Wall of China and all over the world and Teotihuacan was fascinating for me to see. Even more intriguing, no one knows who built it. Aztecs discovered it many centuries after it was abandoned and forever wondered about its origin.

There are older structures and artifacts than 250 years, they're just not European in origin. Like Cahokia Mounds in Illinois: https://cahokiamounds.org/

Arrowheads are an example of something that's not too difficult to find in the wild if you know where to look.

We used to smoke weed on the roman wall behind my friend’s high school. Very popular hangout spot. Lots of people using it for rock climbing practice (you’re not far off the ground and can climb laterally for hundreds of meters).

The local castle, about 1000 years old, is a popular makeout spot for teens.

250 years is longer than the existence of a country called Italy, let alone the Italian Republic. Just like in Italy, the history of people in your area did not start with the founding of your country.

some folks in Europe live in houses older than that!

TBF, so do some folks in the U. S.; though in most cases, just barely.

we have some omega ancient history here in america like possibly 13,000-16,000+ year old history, we just don't have structures that stood the test of time mostly stone crafted tools and hunting weapons and such. but first peoples history goes way back mindblowingly far

I was in Pompeii just 2 weeks ago, the thing that absolutely blew my mind was that there is a section where archeologists are working _right now_ still uncovering more buildings, and you can see them exactly as they are coming out of the ground - I think with the rest of the ruins I've had this feeling that you know, it got somehow cleaned up and repaired a bit for tourists, but nope, you can see in that section of active excavation works that these 2000 years old structures are really coming out of the dirt with the frescoes and mosaics still intact.

And then we went to Paestum, which is an even older Greek settlement in Italy - with the original Greek temples still standing. Mindblowing, and I'm used to old stuff being around(a friend of mine lives in a house where a portion of it is a listed structure dating to the 12th century, it's just a bathroom and a storage room for them lol).

some folks in USA have houses older than that too

Early settlement of Europeans into present-day USA started in earnest in the early 1600s.
