 Turner gives as an example of the domus dei approach the meditation room at the United Nations Headquarters in New York. This space features a block of iron ore illuminated by a shaft of natural light that descends from a skylight. Accordingly, the place speaks of a meeting of heaven and earth, of light and dark, and of the ambiguous history of human beings in their relationship to the earth, in so far as iron ore has been used for the making both of weapons and of ploughshares. And by virtue of the conditions of stillness and dimmed light that obtain here, the room invites a response of quiet, reverential seriousness. In all of these respects there is implied, once more, a correlative phenomenology.
