Skyscrapers are often referred to as civil engineering's "business card." Skyscrapers, also known as "super-tall buildings" or "vertical cities," are a great illustration of human bravado that goes against the grain of nature.

A structure's roof and walls are designed to remain in one place for the duration of the building's existence. Multiple forms, sizes, and purposes can be accommodated by a single structure. Many societal functions are housed within buildings. Those who enjoy traveling abroad will find this wallpaper to be ideal. Only in major urban centers do you find such skyscrapers.

A building is a permanent structure that has a roof, walls, and windows. First, structures were erected for human habitation. Additional buildings were subsequently built to house supplies and host rituals. Leaves and branches were common components of early structures.
