Redcliffe Shot Tower

[1][2][3][4] In 1775, William Watts, a plumber, started converting his house, near St Mary Redcliffe Church, into the world's first shot tower, in order to make lead shot by his innovative tower process.

He did this by adding a tower atop his house, and by excavating a shaft into the soft sandstone below, achieving a total drop of around 90 feet (27 m).

By 1782, the tower was complete and in production, and Watts was granted a patent on his process, which involved pouring molten lead through a perforated zinc pan into water below.

[1][2][5][6] William Watts was declared bankrupt in 1794, but his tower survived various changes of ownership until it was taken over by the Sheldon Bush and Patent Shot Company Limited in 1868.

The tower remained a well-known feature of Redcliffe until 1968, when it was demolished to make way for road improvements.
