That is the entire principle of the shot tower, and in 1799 it was almost the newest industrial idea in Britain. The Bristol inventor William Watts had patented the process less than two decades earlier, drilling holes through the floors of his own house and dropping lead from the attic into a water tank in the basement to test it. By the time Walkers, Parker and Company built their tower in the Boughton district of Chester, the technique had become an industrial standard - and the 168-foot brick tower they raised beside the Shropshire Union Canal was one of the first generation of true shot towers in the world. Today, more than two and a quarter centuries later, it still stands. It is the oldest surviving shot tower in the world, and the only one in the United Kingdom that predates the twentieth century.

Chester Shot Tower: How Lead Becomes Round

As those droplets fall, they pull themselves into perfect spheres - the most efficient shape for surface area, the same physics that ma...

Chester Shot Tower: Why Chester

From the Roman period onwards, lead from mines in north-east Wales - including the major workings at Minera - had been smelted near the city and shipped from the port of Chester out into the Irish Sea trade. When the Chester Canal opened i...

Small arched windows let in just enough light to work by but not enough to disrupt the temperature of the falling lead. The red brick is honest Georgian-industria...

The 157-foot tower at Elswick in Newcastle-on-Tyne, completed in 1797, operated until 1951 and was demolished around 1968. The two London shot towers that appear in John Constable's painting of Waterloo Bridge - both eventually own...

Chester Shot Tower: After the Lead Stopped Falling

It is Grade II*-listed and protected, but redevelopment proposals for the surrounding leadworks site have generated regular controversy - notably featuring in the 2013 BBC ...
