Holland America Line has been marking its 150th anniversary in style, with a series of events that included royalty, local dignitaries, port officials and guests. The cruise line’s flagship Rotterdam arrived in her namesake port earlier this week, where passengers were treated to a gala dinner, and an impressive light display that illuminated Rotterdam’s Erasmus Bridge. The remaining nine ships across the fleet held their own celebrations.

Holland America Line President Gus Antorcha was joined by Her Royal Highness Princess Margriet of the Netherlands, Rotterdam Mayor Ahmed Aboutaleb and descendants of Holland America Line’s original founders. They gathered at Hotel New York, which was home to Holland America Line’s original headquarters from 1901 to 1977.

Gus Antorcha commented: “From those first early days, we built our reputation on the care we provided to every person who stepped on board. And through the decades, whether that person was an immigrant, a titan of industry, a soldier or a vacationer, each of them was treated as though they were a guest in our own home. It is still a hallmark of our brand.

“The fabric of history is woven from the threads of millions of stories, and at the heart of each of those stories is a person,” Antorcha continued. “I am certain that there are many chapters still to be written. And I hope that decades from now, those who come after us will gather on this very spot at Hotel New York to share them.”

Holland America Line presented a commemorative bell that will be permanently displayed at Hotel New York. Princess Margriet poured champagne over the bell, a Holland America Line tradition that is usually reserved for a new ship launch.

The cruise line is also hosting an anniversary sale with up to 25% off cruise fares, reduced deposits and up to $300 onboard credit. Find out more here.
