we do have old buildings here, especially on the east coast, but definitely not as old as european buildings. native americans didn’t build many permanent structures, so much of our cultural landscape starts with european colonization. thus the oldest buildings here would’ve been built around the 17th century, while some buildings in europe could’ve been constructed before common area— ancient greece, par exemple. as far as i know, some of the oldest buildings in my own town are churches from the mid 1800s.
@kbnjr1 the west coast wasn’t really settled— or, at least, heavily populated— until the 19 century with “manifest destiny” and westward expansion. the first main colonizing groups were from europe, which connects to the east coast through the atlantic. so, a lot of the earliest towns were in virginia (and other coastal states in the east,) and the first established town is in florida. states on the west coast, for that reason, have more modern architecture and towns. still, the west coast has large populations today— california has lots of people now, over 30 million.
