They were joined by Prince Charles and the Duchess of Cornwall.
The Royals took a moment on Thursday to remember the lives lost in London’s tragic Grenfell Tower fire. Prince Harry, Prince William, Kate Middleton, Prince Charles, and the Duchess of Cornwall attended the Grenfell Tower National Memorial Service at St. Paul’s Cathedral in London.
The royal family looked somber at the multi-faith service. The service was in honor of the lives lost and to give thanks for the first responders who helped those affected.
Middleton, who is currently pregnant with her third child, wore a button-down black peacoat and dress with a matching hat, while William and Harry each wore black suits.
Adele also was seen in attendance at the service.
The event marked six months since the horrific fire ripped through the high rise building in June. The fire killed more than 70 people and injured even more.
The Royals have shown their support for members of the community affected by the tragedy with both Queen Elizabeth and Prince William visiting the victims.
In a touching moment, Prince William broke royal protocol earlier this year and allowed a grieving woman searching for her missing husband to hug him – an act not normally allowed between civilians and members of the royal family.
