Location: E Commercial Street, Dubuque, IA
The Shot Tower consists of a tapered square-cut masonry hollow column form. The whole structure stands 120’5″ above the current ground level. Seven stories (82’11”) are of Galena Dolemite stone construction, and the uppermost three stories (37’6”) are built of soft red brick.
There is strong evidence that some of the originally exposed column base is now buried, as is an estimated 15-20 feet of stone foundation. The load-bearing masonry walls are progressively reduced from a base width of three feet to just one foot at the top of the tower. The base measures 19’2” square, while the cap measures 12’4” square. The square interior shaft is a consistently square 13’2” x 13’2”.
