They described Ljubljana as a city that: "...might not roll off the tongue for many travelers but it's worth learning how to pronounce as you're bound to hear much more about Slovenia's capital in the years ahead. Ljubljana is already one of Europe's greenest and most livable cities, boasting a friendly cafe culture by day, and vibrant nightlife after the sun sets. This year gives Ljubljana even more reasons to preen, as the city celebrates the 2000th anniversary of the Roman colony Emona on the same site as the modern-day city. Quirky Roman-themed events and exhibitions will take place throughout the year, and the showpiece event 'Ave, Emona!' (22-24 Aug) will transport the city's central Kongresni trg (Congress Square) back in time (slovenia.info). Ready your sword for those gladiator fights (or watch from a safe distance). Plus it makes the perfect base with plentiful, inexpensive buses radiating out of the city to the rest of Slovenia, which is as picture-perfect as Switzerland but much easier on the wallet."
