If you currently think your neighbourhood coffee shop is nice, you might want to stay out of Vienna’s coffeehouses. After you’ve gotten used to these palatial, yet welcoming cafes—and their delicious coffee and Sacher torte—your local café will pale in comparison. Between coffee breaks, visitors can explore Vienna’s Schonbrunn Palace and Imperial Palace. And if you have a chance, catch a performance at the State Opera House—it’s not to be missed.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?

You've probably heard that Guinness tastes better in Dublin (fresh from the factory), but what you may not know is that Dublin is a perfect destination for the whole family. No, we're not suggesting you let the kiddies drink a pint. Instead, take them to the Dublin Zoo, to feed the ducks in Stephen's Green or on a picnic in Phoenix Park. Scholars enjoy walking in the literary footsteps of such writers as Yeats and Joyce, while discerning shoppers have their pick of designer boutiques.

Kilkenny is over 400 years old, but it sure doesn’t show its age.

An endless stream of arts festivals celebrating theater, comedy, bluegrass and dance is constantly pumping the city with new life, toe-tapping energy and international flavor.

There once was an Irish city… You might think "naughty poem" when you hear the word Limerick, but in truth the city inspires so much more than just knowing giggles. Medieval castles and churches give the city a grand feel, while the pubs crawl with lively locals and students who are all craving just one more pint of Guinness. The Hunt Museum boasts a collection of pieces from history's most important and influential artists, while the Foynes Flying Boat Museum will marvel visitors of all ages with its whimsical flying machines.

Originally founded as a Roman city and now home to three UNESCO World Heritage Sites, Seville is bursting with antique charm. The Alcazar palace complex is a stunning collage of architectural styles, and the Cathedral will impress you with its beauty and its status as the burial site of Christopher Columbus.
