The architect here refers to Antoni Gaudí. Dream here refers to Temple Expiatori de la Sagrada Família and Park Guell, both in Barcelona. There are many more examples of Gaudi architecture in the city, but these two were the ones I visited.
Photo here was taken at Park Guell.
The organic shapes that characterize Gaudi's works did not appear so much out of place in the city like Barcelona, with its climate, atmosphere, temperament of the people.
If one is familiar with the rocky mountain outskirt of the city, which is known as Monserrat, the shapes in Sagrada Familiar are not foreign at all.
Nothing man made is truly original. Man has gotten inspiration from the Nature. Thus the originality resides in the Nature.
