Do you have any good tattoo ideas for cities/countries visited?

I already have several tattoos from literature, music, video games, and poetry. There’s a certain look to them and they all mesh very well together. As I’ve been traveling more and more lately, I’ve been thinking about getting a new tattoo at each city (or country) I’m visiting. However, I want it all to look coherent. I don’t like the look of flags or maps. A suggestion I got was just a word or phrase from each place, but that’ll only work if English wasn’t the native language. Any suggestions?
