Hi,
During one of my commercial visits to the scientific-technical services of the University of La Coruña, I was observing from a corridor the great symmetry and multitude of shapes that surrounded me.
The stairs that can be seen in the background, the two side corridors and also the symmetry of some prism-shaped panels that, when seen from the top view, look square.
I hope you like this small contribution to the Qurator's Photo Quest organized by @qurator.
Best regards.
