The Royal Palace of Madrid that we know today is only a shadow of a giant. Filippo Juvarra, architect of the court of Philip V, conceived in 1735 a colossal project: a mass of marble and glass that doubled the size and ambition of the current building. His premature death and the astronomical costs led Charles III to choose a more modest design. Now, 3D modeling and BIM tools allow us to digitally reconstruct that lost masterpiece.
Virtual reconstruction: from paper to parametric model 🏛️
The reconstruction of Juvarra's Crystal Palace is a perfect case study for the BIM workflow. The original plans, preserved in the National Historical Archive, show a floor plan with a 470-meter facade and a huge glazed central courtyard. By modeling in Revit or ArchiCAD, researchers can assign historical materials (granite stone, blown glass) and simulate natural lighting. The result allows us to contrast the structural decisions: Juvarra's central dome, 40 meters high, would have required a buttress system similar to that of St. Peter's Basilica in the Vatican, something that Sachetti's final design drastically simplified. This digital exercise not only visualizes what was not built but also explains why the economical option was the right one.
Lessons from the past for digital heritage 💡
Juvarra's project reminds us that architecture is also the history of decisions not made. BIM technology today allows us to preserve that intangible heritage, offering a virtual laboratory to understand the political and economic context of each stroke. When rendering the Crystal Palace, we not only admire its beauty; we understand how a king's pragmatism shaped Madrid's skyline. For industry professionals, this is the true power of 3D modeling: not only to build but also to interpret.
