Viking has marked the company’s 25th anniversary with a historic celebration in Amsterdam.

To commemorate the milestone, for the first time ever, three classes of Viking ships—a river ship, an ocean ship and the company’s newest expedition vessel, the Viking Polaris—met in Amsterdam and sailed in a special convoy to IJmuiden, Netherlands. Participating in the convoy with the Viking Polaris were the Viking Longship, the Viking Mani, and the ocean vessel, the Viking Mars.

During the Amsterdam event, Viking also named the Viking Polaris and her identical sister ship, the Viking Octantis, which is currently sailing her inaugural season in the Great Lakes. Both ships will spend the Austral summer in Antarctica, before traveling north to the Great Lakes for a series of voyages during spring and summer.

“Today is historic for Viking—to celebrate our 25th anniversary, to have all classes of our ships sailing together for the first time, and to name our phenomenal new expedition vessels. We are very grateful to their godmothers, Liv Arnesen and Ann Bancroft, for honoring us. As renowned explorers who became the first women to ski across Antarctica, they are the perfect choice for ships that are designed for expeditions,” said Torstein Hagen, Chairman of Viking. “I am very proud of what we have accomplished in our first 25 years. And in our view, we are just getting started. Where do we go next? Onwards.”
