Fodor's Expert Review Plaza de España
This grandiose half-moon of buildings on the eastern edge of the Parque de María Luisa was Spain's centerpiece pavilion at the 1929 World's Fair. The brightly colored azulejo pictures represent the provinces of Spain, while the four bridges symbolize the medieval kingdoms of the Iberian Peninsula. In fine weather you can rent small boats to row along the arc-shape canal. To escape the crowds and enjoy views of the square from above, pop upstairs.
