They joined the rest of Britain in observing a minute of silence at midday to honour the victims of the Grenfell Tower fire on the anniversary of the deadly London blaze.
Aside from that somber moment, the day was filled with smiles and cheers as the 92-year-old monarch and 36-year-old former actress paired up.
They wore contrasting colours, the duchess choosing a beige Givenchy pencil dress and the queen in a lime green coat-dress and matching hat. The queen seemed comfortable in the company of the newest senior royal.
Their first stop featured a performance by local schoolchildren in the town of Widnes, near Liverpool.
The two royals were greeted by cheering crowds in the centre of the city of Chester, where they observed the minute of silence.
The queen worked one side of the street, greeting well-wishers, while the duchess walked down the other side, chatting with local residents and showing her wedding ring to one small group.
