An architecture student in Norway has proposed skyscraper burial as a possible solution to the problem of the country’s shrinking burial space. This is not a totally new idea, as this Gizmodo article illustrates. Other cultures have been practicing vertical burial throughout history.
Norwegians, along with many other Europeans, have been recycling their graves for some time, to conserve space. But the practice of wrapping bodies in plastic, introduced in the first part of the 20th century, has prevented bodies from completely decomposing in time for the next generation of corpse burial, leading to the current space limitations.
