Line 9:
The Wythe County Shot Tower is unique for several reasons. Unlike most other shot towers, which were constructed of brick, this shot tower was built of limestone with walls 2.5 feet thick. The thick, solid stone walls not only made the Shot Tower an extremely strong structure, but kept its interior temperature cool and consistent, improving the quality of the shot it produced. Since the shot needed to free-fall around 150 feet to form proper shaped shot, the designers decided to use the natural terrain to reduce the height of the tower they had to construct. They decided to build the tower on the edge of a cliff, and dig a vertical tunnel 75 feet deep, which reduced the height required of the actual tower to 75 feet. At the bottom of the vertical tunnel was a horizontal access tunnel that opened up near the shore of the [[New River]], whose erosion had formed the cliff over millions of years.
