Urbanists:
    Can anyone supply me with the name for those columns of stone which
stand  flanking the entrances to residential sections of a town or
city.  It seems clear that they were part of a planned neighborhood.
They are disappearing fast from the cityscene and I thought it time for
someone to get out and record them.  It would help  immensely  if one
knew what to cll them.
        You help is much appreciated.
John
