The pair were on hand to open the new museum, which will serve as the archive for the British Racing Drivers Club and aims to be an interactive museum for visitors.
Harry and Lewis spent their morning looking at vintage race cars and showing off some of the coolest artifacts from racing history. They were joined by former F1 champion Damon Hill and drivers George Russell and Alex Albon.
This engagement was Harry's final solo outing as a senior royal. Last week, he joined Jon Bon Jovi at Abbey Road Studios in London to re-record Bon Jovi's "Unbroken" with the Invictus Games Choir to benefit the Invictus Games Foundation. On Feb. 26, he also travelled to Edinburgh, Scotland for a summit about his Travalyst eco-travel initiative.
On March 5, Harry and Duchess Meghan made their first UK outing together since announcing in January that they would step down from their senior royal roles. The two attended the Endeavour Fund Awards in London, looking on happily as they helped present awards to servicemembers for their achievements.
We'll see the Duke and Duchess of Sussex again on March 7, when they step out to the Mountbatten Festival of Music in London. Their final joint engagement as senior members of the Royal Family is slated for March 9, when they join the Queen, Prince William, Duchess Kate, Prince Charles and Duchess Camilla at Commonwealth Day services at Westminster Abbey.
