was written as an elegy to King. Release and promotion The Unforgettable Fire was released on 1 October 1984. The album took its name and much of its inspiration from a Japanese travelling exhibition of paintings and drawings at The Peace Museum in Chicago by survivors of the atomic bombs at Hiroshima and Nagasaki, Japan. The band spent a few days driving around Ireland with photographer Anton Corbijn looking for potential locations. The castle depicted on the cover is Moydrum Castle. The band liked the image's ambiguity and the Irish mysticism they saw in it. The photograph, however, was a virtual copy of a picture on the cover of a 1980 book In Ruins: The Once Great Houses of Ireland by Simon Marsden. It was taken from the same spot and used the same photographic techniques, but with the addition of the four band members.

Fletcher added that Eno's production removed some of the "heavy metal" from U2 and replaced "emotion [as] the driving force". Hot Press hailed the arrival of producer Brian Eno as "a bold move". Reviewer Liam Mackey said that the album was "rich and rewarding". In Melody Maker, Adam Sweeting said "The Unforgettable Fire is the other side of the coin from War.
