Correct; the actual place of Jesus' burial is a matter of speculation, as are many of the various sites where Jesus has said to have visited. In recent years, some very credible archaeologists have uncovered what is apparently "the pavement", where Jesus was brought before Pontius Pilate, it was found a number of feet below the current surface. Today, many tourists on Easter Sunday, strive to follow the 'stations' of the cross, i.e. the route Jesus took on the way to Calvary, little knowing that those "stations" were set up
during the last couple centuries.
Many consider the actual place of the burial was in Gordon's "Garden Tomb"! ...And that also, s just an "educated guess'!
