Gotland lies in the Baltic Sea, east of the mainland. The 1,156 square-mile island, Sweden’s largest, is one of the sunniest places in the country and is a popular summer vacation destination for locals. Its remarkably well-preserved medieval capital, the UNESCO-recognized town of Visby, has cobbled lanes, merchant houses and church ruins enclosed by a 13th-century stone wall. Beyond the city, Gotland’s landscape encompasses sandy beaches, pine forests and lush countryside dotted with red farmhouses and fields of poppies and lupines. Fårö, an island just off the northeast tip of Gotland, was home to filmmaker Ingmar Bergman. Its windswept, rugged coastline is studded with otherworldly rock pillars. The unusual geology, history and climate of the island make it unlike anywhere else in Sweden.
