What makes a city "cool"? If it means being loaded with atmosphere, charm, great food and nightlife, yet ignored by the bulk of travelers, then Lisbon deserves consideration as Europe's coolest capital. Here's why.

The southern French port city of Marseille has taken a bad rap for years. It’s known for thefts, violence and organized crime. But the city had a chance in 2013 to clean up its act, by being Europe’s rotating Capital of Culture for the year. The title means money from Europe to spiff up and boost local arts. Apparently it helped bring in more tourists. But the jury is out on whether Marseille is safer now, and whether local artists benefited from all the hoopla.

After outer space, any terrestrial trip has got to feel like a comedown. But this morning, at exactly 10:30 am GMT, Canadian astronaut Chris Hadfied tweeted,“Good morning, Ireland! Happily headed to Dublin and Belfast. Hoping to learn a cúpla focals [a couple of words].” (Some on Twitter proceeded to correct the former International Space Station commander that the proper usage is “focail”.)

While Dennis Rodman is perhaps the most outlandish celebrity to visit an authoritarian regime, he certainly isn't the first. The former NBA star hosted an exhibition game between North Koreans and former NBA players today. He insists his trip is apolitical, although he has repeatedly professed his fondness for Kim Jong-un, his new “friend for life.”

I received a letter from the U.S. State Department last week. It was from a program officer in the office of International Visitors thanking me for hosting three Chinese journalists who were visiting the United States as part of the State Department’s Edward R. Murrow exchange program. It was a very nice thank-you note. The last line read: “Your generosity and kindness made a lasting, positive impression, helping advance the cause of America’s public diplomacy effort.”

The bookshops are stocking up, the hotels undergoing spring-cleans and the pubs preparing to welcome guests keen to follow in the footsteps of Wales's most famous poet and hellraiser. Admirers of Dylan Thomas are expected to descend in droves on South Wales this year not just from across the UK but from the US, Europe and the far east to join a year-long celebration marking the centenary of his birth.

After a week or two in the South Korean capital of Seoul, newcomers often harbor extreme views on the city. They either love it or absolutely despise it. The first cohort can’t get enough of this Asian metropolis of almost 10 million people. They find endless fun in its pulsating nightlife, surfeit of palaces and temples, and cheap vodka-like booze called soju. Hiking up its peaks (yes, Seoul has peaks), they are mesmerized by its never-ending skyline.
