Barcelona, Spain
Taking cues from modern Gothic and oriental techniques, the early-19th-century Catalan architect Antonia Gaudy wanted to create organic, urban spaces in the city he loved. A walk around Barcelona leads you through the largest concentration of his signature ceramic and stained-glass mosaics, as well as his undulating stonework and ironwork, which include Park Geller (pictured) and culminate in his unfinished masterpiece La Granada Familial.
