Designed for Mexico City, a place that already celebrates its dead with unrivaled fervor , this subterranean tower descends into the Earth like something out of Dante, and is designed to help people grieve. It rises slightly above the ground, and at the pedestrian level it looks like an empty hole — "the sensation of vacuum represents the absence caused by death," according to its Mexico-based designers. Mourners would descend along with the casket of their lost loved one, and they would be "reborn" into the light after their trip to the underworld. The tower also solves the problem of where to bury the elderly, especially in overpopulated areas like Mexico City. After a parting ceremony, the caskets are taken to a crematorium.
