They’re rubbish bins (or perhaps textile recycling bins, but probably not) specifically for national, regional, and/or local flags.

American flag worship is a little creepy, honestly.
Religious practice precedes religious belief. The first generation to perform religious practices don’t do it for “religious” reasons. They don’t really “believe” that a flag is a person and that it fundamentally deserves to be treated like one, they just choose to act that way. But when the following generations are raised seeing adults consistently treat a flag like a person, they DO take on religious beliefs towards the flag. And it quickly gets creepy and scary.
TIL, that’s actually make sense
