Westminster Abbey flowers pay tribute to Queen Elizabeth II

Among the foliage decorating the High Altar inside Westminster Abbey are branches from a pair of Dawyck beech trees planted by Charles’ parents, the late Queen Elizabeth II and Prince Philip, in 1978 at Wisley, a Royal Horticultural Society garden.

Throughout the Abbey, over 120 varieties of flowers can be seen. The arrangements were made without the use of single use plastics or floral foam, an ode to Charles’ focus on the environment.

Charles pledges the coronation oath

Charles places his hand on the Holy Bible and says, "The things which I have here before promised, I will perform and keep. So help me God."

The king signs an oath, pledging to serve the people and rule according to law.

The coronation oath marks the only time a monarch signs a written obligation to their people, according to ABC News royalty consultant Alistair Bruce.

Following the oath, Charles kneels before the High Altar and prays. Charles’ prayer is inspired by the hymn, “I vow to thee, my country.”
