Yes and I recommend you Wrocław city museum for a showcase of beautifully thought out plans that never went anywhere even when Wrocław was Breslau. It is the reason I was touched by such a mundane topic that I would not otherwise be interested in.

One of the reasons such plans did not go ahead is that it required a state that can expropriate left and right and amounts of capital not available to localities, even in cities like Wrocław.

Those kind of grand plans only work if there is a national drive that imposes it, or most likely after a war. This is true in Poland Portugal or anywhere developed and desirable.
