As I mentioned last week in my review of the novel The Pillars of the Earth, the late Gothic period in Spain transitioned into a very ornate style of architecture called Plateresque. The New Cathedral of Salamanca is one example of this style.
Up close, you can see the incredible detail of the facades. “Plateresque” means “in the style of a silversmith,” so there are many little flourishes.
There were some renovations of the exterior done in the 90s, and the builders added their own touches, including this astronaut. See him on the left? It is definitely an unexpected detail!
