10. Mind House (Barcelona, Spain)
Park Güell, located just a few steps from Gracia, on a hill in the suburb of Vallcarca. In 1900 Euzebi Guell bought this hill in order to arrange there a private garden city in English style. The areas in the park were designed to be sold for building the mansions and all the infrastructure and public places Guell commissioned to Gaudi. However, the project failed: for those who wanted to live in Barcelona, the park was too far from the center, but for those who wished to live outside the city it was too close. As a result, Güell’s heirs sold the hill to city authorities, who opened the park to the public.
