Fart means speed or travel in Danish. Overfart means crossing. So in this case i'd expect this museum to display artifacts of the town and the ship crossings that left from that city.
There's a street called "Fanny Hands Lane" that we saw when driving home from the seaside when I was a kid. We were all laughing so much, my mum had to pull over. (In the UK, 'fanny' is slang for vulva.)
Many years ago, I was on a road trip and sent my wife a postcard from Cooter, Missouri. I was absolutely crestfallen when it arrived postmarked "Steele" or some boring shit from the next town over. I don't remember if I adjusted my route to pass through Weiner, Arkansas, and therefore I probably didn't, but I should have.
