Fort Worth's previous city hall, which is now the Public Safety & Courts Building, is a nifty little Moderne/Deco building which I quite like.
Unfortunately, the current city hall is a horrific piece of brutalist garbage that is a blight on the area of downtown where it resides.
Fortunately, the city is in the process of coming up with a new City Hall plan. Ideally I'd like to see the current city hall demolished and something better built in its place, but even just removing the current building from active City Hall use would be good.
