It's always wild to me how young the US is. I have personally visited homes older than that entire country.
I love those old buildings in Europe. When the Americas were first being settled (long before the US was founded), ships would pack their lower decks with old bricks from Europe when they sailed to America (known as ballast brick). When they got to America, they’d unload the brick and load the ships with American product and sail back to Europe. The ballast brick would then be used to build buildings here in America. So some buildings in the US actually have very old bricks in them, much older than the buildings they are a part of.
(That was a very clever attempt at sowing fiction between Europe and the US, but it didn’t work. We’re on to Putin’s psyop techniques now.)
