superstructure

Any structure built above the top full deck (FM 55-501).

Any material structure or edifice built on something else; that which is raised on a foundation or basis.

The Wards are open-topped, with skyscrapers rising from the superstructure. Towers are sealed against vacuum, as the breathable atmosphere envelope is only maintained to a height of about seven meters. The atmosphere is contained by the centrifugal force of rotation and a "membrane" of dense, colorless sulphur hexafluoride gas, held in place by carefully managed mass effect fields.

All that part of a building above the basement.

The sleepers and fastenings, in distinction from the roadbed.

The social sphere of ideology which includes religion, art, politics, law and all traditional values.

The superstructure evolves more slowly and is more resistant to change than the economic infrastructure, especially in the modern industrial age of advanced capitalism.
