Phoenix Shot Tower, Baltimore
One of the other memorable sights on our walk was this very tall tower. It's where rifle shot was produced - lead was dropped at the top of the tower, and as it fell into water at the bottom of the tower, it would be perfectly round to work in the rifle.
From what we could see, there were no tours or museum, just a neat building with an equally neat history.
The tower was originally used ot make ammunition. Molten lead was poured through a slotted surface and let drop into a coolant. Along the way, it used gravity to form perfect circles.
Arriving here isn't all that important as you can't enter the tower. There is, however, a small shopping mall, and at the base of the tower is a memorial to Baltimore policemen who have fallen in the line of duty.
This tower, the tallest structure in the US when it was built, was used during the civil war to produce shot.
