A metre-long core from inside the prehistoric stone was removed during archaeological excavations in 1958. No-one knew where it was until Robert Phillips, 89, who was involved in those works, decided to return part of it. For 60 years. Mr Phillips, an Englishman who now lives in retirement in Florida, kept his piece of Stonehenge – first in a plastic tube at his office in Basingstoke and later on the wall at home in the US.
