Prince William remembered his late mom, Princess Diana, during his recent trip to Blackpool.

The Duke of Cambridge was joined by Kate Middleton during the royal engagement. On their way to a seaside resort for a series of public outings, Prince William paused in a touching moment of remembrance for his mother.

Prince William and Middleton gazed up at a large mirror that Princess Diana unveiled to mark the opening of the World Tower in 1992. Upon seeing the mirror, Prince William smiled and said that it’s both fantastic and amazing.

After the touching moment, he shared with Middleton, Prince William and his wife toured the famous Tower Ballroom. While there, they received some information on the history of the Tower by the manager of Merlin Entertainment Kate Shane.

The royal couple was also treated to a performance of a traditional waltz after expressing their interest in seeing it during their trip to the seaside town.

Prince William and Middleton also said that they wish to bring their children to the resort one day.

“There’s so much here the children would love as well. Hopefully next time we’ll bring them back,” Middleton said.

In related news, Prince William also made headlines this week after it was revealed that Princess Diana got upset at her eldest son after Prince William had a surprise outburst due to the interview, she gave about her and Prince Charles’ failed marriage.

During Princess Diana’s 1995 interview, she told Panorama's Martin Bashir that there was three of them in her marriage. This statement did not sit well with Prince William. In the Amazon Prime documentary “William and Harry: Brothers in Arms,” Katie Nicholl said that Prince William called his mom in a fury and rage after hearing the interview.

“She told me it was the one time William turned on his mother and said that he would never forgive Diana for what she’s done,” Simone Simmons, a close friend of Princess Diana, said in the documentary.
