Vadstena Castle
Vadstena Castle (Vadstena Slott) in Östergötland is Sweden’s best-preserved Vasa Renaissance fortress. Built in 1545 by King Gustav Vasa to defend Stockholm against potential southern invasions, the majestic moated castle was later converted into a lavish royal palace. Rich in royal drama, madness, and political conflict, the castle is famous for its lingering royal apparitions.
