The publication of "Round Church or Windmill? New Light on the Newport Tower," by Danish archaeologist Johannes Hertz, in issue #235 of Newport History, has reopened the debate over that enigmatic building. Particularly controversial were the results of carbon-14 testing of mortar samples from the Old Stone Mill, which placed the date of construction of the tower at about 1665. The author in this article claims that the process of dating mortar through carbon-14 testing has inherent flaws. Until these questions can be resolved a pre-Columbian origin for the Newport Tower cannot be excluded.
