That's Vienna skyline - from Wienerberg to Wienerwald to Simmering power station and Millenium tower, then the Uno City skycrapers, and finally Schwechat refinery.
And what you see below is Rauchenwarth skyline, from fields to gravel quarry to farms and houses to fields; not even a church you might say.
Both shots were taken from the same place, and I must say that I prefer the Mannswörth shot.
