Not even a pair of Just Stop Oil activists, who were arrested after they tried to disrupt the wedding, could dampen spirits.
The activists – an NHS nurse and a care worker – let off a fire extinguisher, spraying orange powder as the newlyweds left Chester Cathedral.
In the nearby village of Eccleston, residents threw a small private party at the town hall on Saturday to mark the occasion.
The Duke, known to his friends as Hughie, inherited his title on the death of his father, Gerald, in 2016, and with it control of a fortune worth an estimated £10 billion.
But since their engagement was announced last April, the couple have been at pains to insist that the Chester community where they will put down their roots would be at the heart of their celebration, funding the distribution of free ice creams and donating the flowers to local charities.
His bride, who grew up in London and Oxfordshire, has worked in the sustainable food and drinks industry, most recently at Belazu, a London-based artisanal food company.
The Prince of Wales and the Duke of Sussex were ushers at the wedding of his sister Lady Tamara Grosvenor at the cathedral in 2004.
Meanwhile, it has been revealed that a 90-year-old academic living in Australia could become the saviour of the Duke’s family title first bestowed on his ancestors at William IV’s coronation in 1831.
If the newlyweds do not have a son, the historic Duke of Westminster title will die with him.
However, his subsidiary title, the Marquess of Westminster, will live on through the Earl of Wilton, his fourth cousin once removed, who lives in Melbourne and also happens to be related, through marriage, to Ms Henson.
