UNESCO enlisted Visby is perhaps the coolest town in Sweden, and certainly one of the most pleasant. For one thing, it’s enclosed by a thick stone wall, with several relatively intact portals and towers, dating back to the 12th and 13th century. The town itself consists of cute little stone and wooden houses, cobble-stone streets (only residents may drive here in summer), an abundance of roses and gorgeous views of the Baltic Sea. Add a host of cafes, restaurants, craft and deli shops and nearby beaches, and you’ve got your perfect summer destination. Because that’s what it is: a summer destination. In July, downtown Visby never sleeps as the party moves here from Stockholm, and in August the town goes medieval-crazy. But quiet corners are never far away, and if you visit in winter, although far gloomier, the snow-covered stone ruins are no less beautiful.
