Prince Philip, 96, looks dashingly dapper!
Buckingham Palace released a new portrait of The Duke of Edinburgh via Twitter on Monday, in celebration of His Royal Highness' retirement from his public engagements.
In the portrait, shot by Australian born artist Ralph Heimans, Philip looks exquisite wearing Denmark’s highest-ranking honor, the sash of the Order of the Elephant. The picture was snapped in the Grand Corridor at Windsor Castle.
The portrait will be on display at the Natural History Museum at Frederiksborg Castle in Denmark, in a special 2018 exhibition of Heimans' work.
"Part of the exhibition explores the historical connections between the Royal Families of Great Britain & Denmark," a tweet from Buckingham Palace explained. "Windsor Castle holds special significance in regard to The Duke of Edinburgh's ancestry. At the end of the Grand Corridor is the Tapestry Room where His Royal Highness' mother, Princess Alice, and maternal grandmother, Princess Victoria were born."
As ET previously reported, Buckingham Palace announced in May that Prince Philip would no longer carry out public engagements starting this fall after seven decades of royal service.
"In taking this decision, The Duke has the full support of the Queen," a statement from Buckingham Palace said. Prince Philip attended one of his final royal engagements in July, the Duke of Edinburgh Awards ceremony in Scotland, an event that honors youth achievement.
