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.

Also if one expands it to the Americas more broadly it goes back pretty far. Earlier this year on a trip to Central America I stayed in a home that dated to the mid-16th century. Still not as impressive as what Europe has, but was neat!

Those are very cool. Worth a visit if you’re ever in the St Louis, Missouri area.
