Minneapolis has several historic water towers. This oneabove is called The Witches Hat tower, and is located on the highest point in the city. The view from there is gorgeous.
Here's the other one, called The Washburn Water tower, named for the neighborhood that it looms over, and my old high school. The stone carvings on this one are make it look very ominous if you stand directly underneath. Both of them are prime tourist spots and very lovely places to be.
