I suppose this really should be labeled worst former landmark since the infamous fountain hasn’t been anchored in the river for over a dozen years. When it first appeared, it was compared to St. Louis’ Gateway Arch. The last time I checked, however, they didn’t take down the Arch during part of the day or put it in storage anywhere.
Perhaps you have a photo of the skyline from the 1980s with the fountain; that actually makes the picture an interesting novelty. Ample parks, a good arts community, and innovative architecture help define a city much more than a floating hose. Oh well, it’s our communal equivalent of New Coke.
