Situated in Melbourne's Central Business District, Coop's Shot Tower is a survivor from a much more industrial past - in an area that these days is all about shopping and offices. Dating back to 1889 and standing at a proud 50 metres tall (for many years the tallest building in the city), the tower was used in the production of lead shot. The process involved dropping molten lead through a sieve at the top of the tower. As it fell the height of the tower, the lead formed spherical balls due to surface tension - which in turn were cooled as they landed in water at the bottom. This apparently bizarre and cumbersome process was nonetheless capable of producing a pretty large volume of lead shot - though it must have been quite an effort to drag all the lead up the tower! The structure remained in use until 1961 but in time came close to demolition as the area was redeveloped. Happily, there was sufficient interest in its history to cause the city's authorities to require developers to preserve it, and it eventually saw a shopping centre built around it - a process which involved covering it with a conical glass roof. Quite an odd and striking sight!
By the way, I came across this while researching the structure. A 1950 newsreel piece about how shot towers work...
