Large building projects have a habit of becoming part of the landscape. Consider big bridges or mountain pass roads and railways: in the perception of those who experienced both the before/after they surely all ruined that view, but to those coming after them, the same structures tend to be a highlight.

In the Swiss Alps, people take far more pictures of the Landwasser Viaduct than of the untouched parts next to it. This is an extreme example (because it's so exceptionally pretty), but the same is true to an only slightly lesser extent about most other things that have been built into those nice landscapes. (the dark cavities of the new Gotthard that dominate the view from the old Tremola are a rare exception)
