Viaduct In Park Guell,Barcelona Editorial Image

Roadways around the park to service the intended houses were designed by Gaudí as structures jutting out from the steep hillside or running on viaducts, with separate footpaths in arcades formed under these structures. This minimized the intrusion of the roads, and Gaudí designed them using local stone in a way that integrates them closely into the landscape. His structures echo natural forms, with columns like tree trunks supporting branching vaulting under the roadway, and the curves of vaulting and alignment of sloping columns so that the inverted catenary arch shapes form perfect compression structures
