Brief SynthesisThe Hanseatic Town of Visby is a unique example of a northern European medieval walled trading town with a preserved and notably complete townscape and assemblage of high-quality historic structures. The ‘inhabited historic town’ includes the walled town and its immediate surroundings constituting an area of 105 ha. Criterion (iv): The Hanseatic Town of Visby is an outstanding example of a North European medieval walled town which reflects with remarkable completeness its essentially late 13th-century form and function as one of the most important trading towns of the Hanseatic League between 1161 and 1360. The visual integrity of the walled town and historic skyline is vulnerable as the town expands and develops. The well-preserved dry moats and open spaces surrounding the walled town form a fringe belt that accentuates and distinguishes the compact medieval town.
