Ancient documents have revealed that in most instances it took numerous years, usually decades, for even one of the ancient Egypt pyramids to be assembled. Records also indicate that it was traditional for a pharaoh to begin construction on a pyramid not long after he took the throne and that the building process might last almost the entire length of this reign. In the case of King Tut, evidence indicates that the tomb he was not expected to die at such a young age and therefore did not have sufficient time to prepare his own burial tomb.
