Shotwell Tower, overlooking the tidal River Hull, in Hull, Humberside, East Yorkshire, England UK

---

Shotwell Tower was built for making lead shot using the drop method. The process was patented in 1782 by Bristol plumber William Watts, who realised that if drops of molten lead fall far enough through the air into water they become spherical: a significant improvement on the shape and quality of lead shot produced through casting.
