Ono was joined by her son Sean Lennon, Ringo Starr and George Harrison’s widow Olivia at the event in Iceland.

Surprisingly, Lennon’s fellow Beatles bandmate Paul McCartney did not attend.

Ono dedicated the Imagine Peace Tower – a 65ft tall wishing well that beams out a blue ray of light – to her late husband on what would have been his 67th birthday.

The 74-year-old artist said: “I hope Imagine Peace Tower will give light to the strong wishes of world peace from all corners of the planet and give encouragement, inspiration and a sense of solidarity in a world filled with fear and confusion.

“I consider myself very fortunate to see the dream my husband and I dreamt together become reality.”

Lennon’s iconic track Imagine was played as Ono proudly unveiled the instalment.

The tower, situated on a volcanic island in Reykjavik’s harbour, is engraved with the words “imagine peace” in 24 languages.

100,000 people from all over the world will put a wish in a capsule which will be buried around the tower.

Ono chose to erect the tower in Iceland because of the country’s environmental policies and reputation as a peaceful nation.

The sculpture will be illuminated each year on Lennon’s birthday until the anniversary of his death on 8 December. It will also light up on New Year’s Eve and the first week of spring.

Lennon was shot dead outside his New York apartment building by Mark David Chapman in 1980.
