The quaint town of Visby, a UNESCO World Heritage Site, is ringed by a 13th-century limestone wall, encasing the best-preserved medieval city in Scandinavia. A four-hour adventure encompassing many of its highlights begins with a motorcoach drive to a former gallows site. Then, embark on a walking tour of Visby, crossing through the eastern side en route to the Dalmansporten gate. Head down narrow streets to the 13th-century St. Mary Cathedral, still in use today. Pass through the old Hanseatic harbor at Almedalen to see the oldest remaining structure in Visby, then reboard your motorcoach for a panoramic drive through the agricultural district to photograph the rural medieval churches that dot the landscape. Continue to Gnisvärd, a picturesque old fishing village, and see the unusual Gnisvärd boat shaped graves, dating from the Bronze Age (about 600 BC). Return to port after this lovely and informative day.
