Casa Vilaró is an iconic property and one of the earliest examples of rationalist architecture in Spain, designed in 1929 by architect Sixte Illescas. Located in the Gràcia district and just steps away from Gaudí’s famous Park Güell—a prime expression of Barcelona’s natural beauty and modernist art—Casa Vilaró stands out with its avant-garde design of clean lines and white façades, a true milestone of its time.
