When Antoni Gaudí received his degree from the School of Architecture in Barcelona in 1878, the Director, declared: “I do not know if we have awarded this degree to a madman or to a genius; only time will tell.” Indeed, time has told of Gaudí’s genius when seven properties designed by him –Parque Güell, Palacio Güell, Casa Mila, Casa Vicens, Gaudí’s work on the Nativity façade and Crypt of La Sagrada Familia, Casa Batlló, Crypt in Colonia Güell – were given the UNESCO World Heritage Site status. As per UNESCO, these monuments represent an eclectic, as well as a very personal, style which was given free rein in the design of gardens, sculpture and all decorative arts, as well as architecture. Explore these inimitable, and quirkiest of Europe’s World Heritage Sites and decide for yourself whether Gaudí was a genius or a madman.
