For a while, France had its own prime meridian with 0 degrees passing of course through Paris: https://en.wikipedia.org/wiki/Paris_meridian

It still does. I have one going through my house too. The problem is nobody else knows or cares about those meridians. It's quite fortunate the US didn't invent its own, what with its zeal for being different. We're quite lucky to still have just the one.
