Gargoyles and grotesques of long ago were frequently scary images of monsters and mythical creatures. Today as some places replace ones that are wearing down in the elements, they may put in place ones based on real people or even characters from stories. One such place that is doing that is that National Cathedral in Washington, D.C.
I heard they had a Darth Vader grotesque. I asked the guards at the Cathedral where it was located. They answered look on the dark side. They didn’t seem so sure of its exact location themselves. I had to ask someone wandering around. It is high up on the dark side of northwest tower of the cathedral. It is very high up and one would need good binoculars to locate it.

Gargoyles have pipes going through a section of their body, usually the mouth. The purpose is to lead the water away from the building.
Grotesques are like gargoyles, except they are more for decoration. They do not have a pipe protruding from a mouth.
Many go to the cathedral to see the interior. If you plan to visit, bring a good pair of binoculars or a zoom lens. It is worth looking up.
