Seven properties built by the architect Antoni Gaudí (1852–1926) in or near Barcelona testify to Gaudí’s exceptional creative contribution to the development of architecture and building technology in the late 19th and early 20th centuries. These monuments represent an eclectic, as well as a very personal, style which was given free reign in the design of gardens, sculpture and all decorative arts, as well as architecture. The seven buildings are: 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.
