The Newport Tower, or Old Stone Mill, is an incredible structure. Regardless of which theory you believe on the creators of the tower, it has amazing astronomical alignments and other hidden treasures buried in the stonework. My wife and I went to the tower for the Winter Solstice events. Early in the morning, Newport Tower Museum curator, Jim Egan, was on site to provide wonderful information. I would also highly suggest visiting his museum during your visit. This impressive stone structure is a free attraction and well worth visiting.
