Maybe this is symbolic — the U.S. Capitol contains a pair of “doors to nowhere” that serve no purpose.
In 1901 sculptor Louis Amateis designed a set of bronze doors to grace the reconstructed façade of the building’s West Front. But when the doors were cast in 1910, legislation for the improvement still had not been authorized, so they couldn’t be installed.
The “Amateis Doors” were displayed in various museums until 1967 and then placed in storage. They were finally hung in the Capitol in 1972, just downstairs from the Rotunda … where they seem to promise great things but ultimately lead nowhere.
