Gotland's capital, Visby, is a delightful hilly town of about 22,000 people. Medieval houses, ruined fortifications, churches, and cottage-lined cobbled lanes make Visby look like it's from a fairy tale. Thanks to a very gentle climate, the roses that grow along many of the town's facades bloom even in November.
In its heyday Visby was protected by a wall, of which 3 km (2 mi) survive today, along with 44 towers and numerous gateways. It is considered the best-preserved medieval city wall in Europe after that of Carcassonne, in southern France. Take a stroll to the north gate for an unsurpassed view of the wall.
