Hello dear @garvi. The twin towers of the Torres de Hércules is definitely an outstanding monument. Interestingly, it could have been easier for the Architects of that project to just stick with purely glazed exteriors to speed up its completion, right? However, I believe that the incorporation of the tower's concrete latticeworks is what makes it truly exceptional. Aside from its decorative purpose, it's cleverly designed to act as sunshades during the summer months to help control overheating in the building's interiors. For the untrained eye and for the general public, they might have the initial impression that those exterior patterns signify the modern versions of Egyptian hieroglyphics but are in fact Greek letters once discovered. As a result, the interplay of figures causes a dynamic effect in the shadows and reflections of that skyscraper.
Do you have some clues on how they constructed those concrete latticeworks? Were they precast components or were they assembled on-site? Was it a tedious and meticulous job?
They were built on site, effectively a specific work of polystyrene moulds for the formation of the letters of the facade. A tedious job, as you say, but a surprising result.
A delicate process that has finally been left as an example.
Oh, amazing! Truly, that particular construction process must have taken a lot of patience, intricacy, and determination to achieve that building's spectacular aesthetics. At the end of the day, we get to experience the enjoyable architecture from that marvelous labor of love. Have a gorgeous day my friend! 😊
