Situated on the Channel Highway is one of the State's most historic buildings, the Shot Tower. The Shot Tower is a 48m (157ft) tall, 10m (32ft) in diameter circular sandstone tower constructed by Joseph Moir in 1870 from locally quarried sandstone blocks. Lead shot was made by dropping molten lead through a sieve at the top of the tower and by the time it hit the water at the bottom it was cold and spherical in shape. A climb up 259 steps to the top of the tower gives a wonderful view of the Derwent Estuary. ( http://en.wikipedia.org/wiki/Taroona )
