Definition of polygonal:
To this place the resort of pilgrims was formerly very great; and, though considerably diminished, there are still to be seen in the summer a few in the water, in deep devotion, up to their chins for hours, sending up their prayers, or performing a number of evolutions round the polygonal well; or threading the arch between well and well a prescribed number of times.- "A Select Collection of Old English Plays, Volume I.", R. Dodsley.

Massive towers of defence, at first round, then polygonal, then square, flanked the west fronts, veritable keeps, where the sacred vessels and relics might be preserved and defended in case of attack.- "The Story of Paris", Thomas Okey.
