Park Güell,Barcelona:

The architect Antoni Gaudí (1852-1926), the most representative of Catalan Modernism, designed it commissioned by the entrepreneur Eusebi Güell. It was inaugurated as a public space in 1926, although initially it was going to be a development with luxury homes. The park covers an area of 17.18 acres along a vertical drop of 60 meters. It consists of several elements such as entrance pavilions, staircase with dragon made of "trencadís", the hypostyle hall with 86 fluted columns (6 meters high and 1.20 meters in diameter each one), the oval piazza of 3,000 m2 with its undulating bench of 110 m. in length, the viaducts, The Calvary (which replaced a chapel monument never built) and the Gaudi house museum. The design represents a diagram of forces acting over the porches of the viaducts.
