Juxtaposition

The photos I have selected all have on thing in common. They are opposite to their surroundings.

For example this plaque and a stone monument is clearly man-made and is doesn't match it's surroundings as it is all natural.

This grid is located in the middle of a grass patch which I find to be opposite to it's surroundings. It is man-made and therefore doesn't match it's natural surroundings.

The shoe of this statue I believe fits the same principles. The rest of the statue has become worn and no longer resembles the clean and shiny metal that the shoe displays. This I believe shows opposites.
