Newcastle and Coventry

These two English towns feature in some relatively common English expressions. (These are not generally understood in North American English, however.)

We talk about "carrying coals to Newcastle" when we want to say that an activity is redundant. This is because Newcastle (or Newcastle upon Tyne, to give its full name) was a coal-mining centre [AmEng center] and certainly didn't need any additional coal!

Being "sent to Coventry" means being given the "silent treatment". That is, you're punished by being ignored, with nobody speaking to you. Yuck! Read about St. John's Church, the origen of the phrase.

To give an expression with an American location, how about "in a New York minute", as in very quickly, in a very short period of time.
