The result of Gaudi´s research is a tree-like column structure. The columns are inclined and branched-like trees. The weight will be routed directly over the pillars in the ground - all this without bearing facade or exterior buttresses. The result of this ingenious solution is spectacular: the pillars and arches supported by them transform the interior of the temple into a stone forest of palm trees, lots of light streaming in through large windows and the vault.
