Kosice, Slovakia The somewhat lesser known of this year's European Capitals of Culture is quite a gem in its own right. The second-largest city in Slovakia behind Bratislava is a melange of Gothic cathedrals, Baroque theaters and remnants of city walls dating back to the 11th Century. It's also teeming with artwork, which all goes on display for the Night Of Museums and Galleries celebration and the Use The City festival of public art, both in May. Though no longer as inexpensive as before switching from its koruna to the euro five years ago, Kosice and surrounding Slovakia are still the gorgeous and relatively undiscovered gems of Central Europe. Unless visitors enjoy a brisk day for sipping mulled wine and enjoying local beers, this Capital of Culture is best enjoyed between May and September, when it's slightly less gray and frigid.
