The naming ceremony of the Viking Mars took place on May 17, in Valletta's Grand Harbour attended by friends and business partners of Viking, including Maltese officials.

The ship's ceremonial godmother Lady Fiona Carnarvon, the Countess of Carnarvon, offered a blessing of good fortune and safe sailing for the ship—a naval tradition that dates back thousands of years. This week the new ship will begin her maiden season sailing itineraries in the Mediterranean, Scandinavia and Northern Europe, before repositioning at the end of the year for voyages around Australia and New Zealand.

"It is always a proud day when we welcome a new sister ship to our fleet. The Viking Mars will allow us to offer even more opportunities for curious travellers to explore the world in comfort," said Torstein Hagen, Chairman of Viking. "Many of our guests were introduced to both Viking and Highclere Castle while watching Downtown Abbey, and over the years we have continued a close friendship with the Carnarvon family as they have welcomed our guests into their home. We are very grateful that Lady Carnarvon has honoured us by serving as godmother of our newest ocean ship."

"I am honoured and privileged to be the godmother of the Viking Mars. I have no doubt she will delight the many guests who travel with her around the world. For more than a decade, Viking and Highclere have been linked through both Downtown Abbey and life, and we look forward to continuing welcoming the extended Viking family to explore our home for years to come," said Lady Carnarvon.  

Lady Carnarvon offered her blessing for the ship via video from Highclere Castle, and a bottle of Norwegian aquavit was smashed on the ship's hull. As all Viking ocean ships are registered in Bergen, Norway, the event paid tribute to Norwegian Constitution Day—May 17—and featured a performance by Norwegian singer Sissel Kyrkjebø, who is widely considered one of the world's top crossover sopranos and is also the godmother of the Viking Jupiter. Valletta is significant as the location for the ship's naming, as Malta was one of the first countries to welcome Viking ships when the company restarted operations in 2021.

In lieu of a large-scale event, Viking and Lady Carnarvon jointly decided to celebrate the naming of the Viking Mars and Viking's 25th anniversary in a private and more meaningful way— donating GBP10,000 each to 25 worthy charities covering a spectrum of causes that are important to both Viking and the Carnarvon family.
