And we europeans consider them young. What we are pointing is that people in US (and America in general) talks about pre-1776 stuff as they were prehistoric, and pre-1900 stuff as they were comparable to Roman ruins. Add to that that we love to bomb each other to a ruble, and buildings and countries younger than 200 years are viewed as temporary stuff. Nothing pedantic or snobby here, just pointing that we live in different scenarios that affected our views.

It’s more like US people look at a couple 100yo buildings and say stuff like “wow this place has a lot of history!”
