Casa Batlló, Barcelona, Spain Sam I Am would not like his green eggs and ham eating slow, or with his toe, or ordered to-go. But he might like them at Casa Batlló. This building is one of several around Barcelona designed by Antoni Gaudí. Like Dr. Seuss, Gaudí almost never used straight lines in his constructions. The Casa Batlló is, arguably, his most Seussian work.
