Architectural Jokes
overly-large Keystone that destroys canopy pitch

Keystone


Architectural oddities include "jokes" such as purposely incorrect doorway lintels and keystones. The "Palazzo di Té" is located at Mantua, and the Venetto is well known for its architectural achievements! These doorway lintels were not errors! Note the yellow line that shows that the roughly-hewn keystone has been raised, thus forcing the canopy pitch to be steeper, resulting in a canopy that is forced to separate (red arrow).
