Nature’s Grandeur

Gaudí’s fascination with nature is evident throughout the Sagrada Familia. Here are a few major traits that demonstrate this:

Curvilinear Forms

Gaudí inserted secret messages throughout the basilica. For example, the turtle and salamander sculptures on the front depict land and water, respectively, representing the earthy and spiritual realms.

Gaudí used an inverted model to find the best angles for the basilica’s columns and arches. This involved hanging weights from a maquette to simulate the forces occurring on the real building.

Hyperboloid Columns
