Once a strategic point for European merchants due to its proximity to the Baltic Sea, the old medieval town of Visby is filled with beautiful architecture. On the Swedish island of Gotland, one building in particular stands out: the Visby Cathedral.
Originally built as a church dedicated to St. Mary in the 12th century, it was rebuilt in the 13th century by the Hanseatic League, an organization formed by German merchant guilds. At that time, it dominated commercial activity in Northern Europe, and many Germans lived in Gotland.
