The Imagine Peace Tower is a dramatic and moving memorial to John Lennon that was built by Yoko Ono on Viðey Island just off Reykjavik, Iceland. The monument consists of a round stone base with the words “Imagine Peace” inscribed in 24 languages and a light installation that reflects a powerful beam 10 meters wide and 4000 meters high. Although it’s possible to visit the memorial all year round, it is only illuminated from October 9th (the date of Lennon’s birth) through December 8th (the date of his murder) and also on the Winter Solstice, New Year’s Eve, and for one week during the Spring Equinox.
