The Shot Tower in the Melbourne Central Complex

This is one of the buildings that my daughter and I visited when we were on holiday in Melbourne, Australia.

Melbourne Central is a large shopping, office, and public transport hub in the city of Melbourne, Australia. The complex includes the Melbourne Central Shopping Centre; the Melbourne Central railway station (a part of the City Loop underground railway and formerly called Museum); and the 211m-high office tower known to locals as the 'Batman building' due to its distinctive black colour and bat-like communications masts.

Contained underneath the shopping centre's massive glass cone sits the old Shot Tower which originally operated on the site. The tower was retained to become a focal-point of the centre.

What is a Shot tower?
With help from Wikipedia, the free encyclopedia:

A shot tower is a tower designed for the production of shot balls, which were used for projectiles in firearms. It replaced the earlier techniques of casting shot in molds (expensive) and dripping lead into water barrels (out of round).

In a shot tower lead is heated until molten, then dropped through a copper sieve high inside the tower. The liquid lead solidifies as it falls and by surface tension forms tiny balls. The partially cooled balls are caught at the floor of the tower in a water-filled basin. The now fully cooled balls are checked for roundness and sorted by size; those that are out of round are remelted.

You can see more of the Shot Tower in the Workshop.
