Ruin Value
Ruin value (Ruinenwert) is the concept that a building be designed such that if it eventually collapsed, it would leave behind aesthetically pleasing ruins that would last far longer without any maintenance at all.
The idea was pioneered by German architect Albert Speer while planning for the 1936 Summer Olympics and published as "The Theory of Ruin Value" (Die Ruinenwerttheorie), although he was not its original inventor.
The idea was supported by Adolf Hitler, who planned for such ruins to be a symbol of the greatness of the Third Reich, just as Ancient Greek and Roman ruins were symbolic of those civilizations.
