So you used the Christmas break to take that long-desired trip abroad? And you came back with those wonderful memories of a café au lait in Paris, a gondola ride in Rome or those lazy afternoon on Brazil's beaches?

Now that you're back to reality, you might want to hang on to those magic moments as you put in the hours at the office. Why not adorn your smartphone with a case that pays homage to one of those great cities you graced with your presence? And if you did not pick up the protective cover in Beijing or Delhi, don't despair. Thanks to the Internet, you can simply have it shipped to your home.

We have compiled some of the most beautiful options from some of the world's most amazing places:

  • Who could ever forget a trip to Paris? And that amazing view you had from the city's most famous landmark, the Eiffel Tower. But for a constant reminder, check out Skinit's Autumn Trees case for your iPhone 6 Plus. It's as classy as the city itself, but (unlike Paris) turns out to be quite affordable at $14.99.

  • What better way to explore London than aboard one of its world-famous red double-decker buses. (After all, driving is a challenge on the wrong side of the road.) And sure, you took one of those to bypass Big Ben. That moment, captured on Etsy's London case, is yours for $15.92. And look what other classic is right there as well: One of the city's traditional black cabs!

  • If Europe turned out to be too cold for you in the winter, and you instead headed to the sunny beaches of Rio de Janeiro, consider Zazzle's Brazil Barely There case. It features the unique, Portuguese-inspired Copacabana pavement you so recently strolled on. And it's yours for $50.95 if you own a standard iPhone 6, or $56.95 if it's for the iPhone 6 Plus.

  • You spent your holidays sipping sake and indulging on sushi? Then you'll surely appreciate a reminder of the astonishing architecture of Japan's capital. Fine Art America's Tokyo Skyline case will do just that, and it'll set you back $35, no matter which iPhone model is yours.
