The main feature of this tiny but lovely tree-shaded park, which occupies the site of a collapsed colonial building, is a sculpture given to Fidel Castro by Ecuadorean artist Oswaldo Guayasamín (1919-1999), whom the park honors. Rumiñahui was the last Inca emperor who fought a tenacious guerrilla war against the Spanish conquistadores; it is a Quecha word for “Eye Stone.”
