Bones belonging to two children were discovered in 1674 by workmen rebuilding a stairway in the Tower. On the orders of King Charles II, these were subsequently placed in Westminster Abbey, in an urn bearing the names of Edward and Richard. The bones were reexamined in 1933, at which time it was discovered the skeletons were incomplete and had been interred with animal bones. It has never been proven that the bones belonged to the princes, and it is possible that they were buried before the reconstruction of that part of the Tower of London. Permission for a subsequent examination has been refused.
