The major building left over from the Exposición Iberoamericana at the Parque María Luisa is the crescent-shaped Renaissance-style structure set on this landmark square. Architect Aníbal González not only designed but supervised construction of the immense structure. You can rent rowboats for excursions on the canal, or you can walk across bridges spanning it. Set into a curved wall are alcoves focusing on the characteristics of Spain’s 50 provinces, as depicted in tile murals.
