This may what the Tomb of Jesus may have looked like. Bodies were placed in these tombs until all that was left were bones. Then the bones would be gathered up and placed in a bone box with the name of the person inside etched on it. The tomb would then be made ready for the next person.
A rich man like Joseph of Arimathea would have had a tomb like this and it would not have been any where near where the Romans did crucifying.
