OK, not a skyscraper or even a commercial building but somewhat important for the area. The Moline Preservation Society was formed in 1986 by concerned citizens to try and save the perfectly preserved 1858 Huntoon House from demolition by it's owners. The owners, a church, opted to take the "fuck-you" attitude towards the society and the citizens of the city and demolished the house, ceiling murals painted by Swedish artist Frank Lundahl, anyway. An ugly, windowless, addition to the church and a small parkinglot fill this space.
The preservation society vowed to never let this happen again, and after the thrashing the church got from the whole Quad Cities, it probably won't.
