Drive along the elegant Passeig de Gracia with its wrought-iron street lamps and fine array of Modernist buildings, including Gaudi's Casa Mila, with its arches and spiral chimneys. It is known locally as "the stone quarry," because of its wavy facade of rough stone. Originally designed as an apartment building, it now houses a cultural center. Stop for a photo of Gaudi's controversial and towering masterpiece, La Sagrada Familia (The Holy Family) Church. Begun in 1883, it is still unfinished.
You'll enjoy spectacular views of the harbor and the Olympic Stadium from the top of Montjuic before descending to explore the Gothic Quarter. Stroll this island of narrow, winding streets of stone and magnificent historic buildings in the middle of a modern metropolis. Stop to admire the facade of the stunning cathedral, richly decorated and adorned with gargoyles.
