Vadstena castle is one of Sweden’s best preserved buildings of Renaissance architecture, built in the 1500s by the Swedish King Gustav Vasa. In this poster, made in the 1930s, you can see M/S Juno gliding past the castle in all her glory. M/S Juno was built in 1874 in Motala and holds the title of the world’s oldest cruise ship. And still today, 150 years later, she is in use!
