The widow of John Lennon, Yoko Ono, is to unveil a peace tower dedicated to the late Beatle in Iceland on what would have been his 67th birthday.
The couple discussed the peace tower concept in the 1960s
The light tower, engraved with "imagine peace" in 24 languages, will go on display in Reykjavik on 9 October.
The musician predicted 40 years ago that the tower, which is designed by Ono, would eventually become a reality.
Some 100,000 wishes from people around the world will be placed in capsules and buried around the installation.
"I consider myself very fortunate to see the dream my husband and I dreamt together become reality," said Ono.
She added that she chose Iceland for the site of the tower because "it is a very unique, eco-friendly country".
"Like-minded friends from all over the world" have been invited to join the 73-year-old for the unveiling ceremony next month.
