Concrete Outline of the USS South Dakota (BB-57)

When they scrapped "Old Nameless" in 1962, Sioux Falls couldn't get the whole battleship into landlocked South Dakota. So they salvaged what parts they could, poured a foot-high concrete outline onto the ground in Sherman Park along the banks of the Big Sioux River, and combined the pieces into a minimalist pseudo-replica.

The anchor, the ship's bell, a massive propeller, and other components are placed around the park within the outline. There is an original 16-inch gun (weighing 94 tons), suitable for shelling the towns of eastern South Dakota, and the actual flag mast. The outline is 680 feet in length.
