Not far from hence, on the top of a hill, is an ancient Tower; its form is circular, its height about 20 feet, the diameter 12; its walls compose only two thirds of a circle, the rest is open. In all probability it was a Watch Tower, and connected with Diganwy as a place of retreat. The name of this District, Creuddin, seems to be derived from Creu, or Crau, blood, or gore, and Din, or Dinas, a fortified place; and was so denominated, in all probability, from the many bloody battles fought here between the English and Welsh. The fine view of Conway Castle and the Bennarth woods, from this side of the river, is greatly and deservedly admired.
