The granite monument dedicated to Miguel de Cervantes was erected in honor of the third most important centenary of Spanish literature: "Don Quixote". Under the stone figure of the writer you can see his literary sons in bronze, Don Quixote and Sancho Panza, and to make the playing field even they've been joined by the novel's two main female characters, Dulcinea and Aldonza.
FUN FACT: if you look closely at the Cervantes monument, you can also see the five continents depicted, symbolizing the universality of this work, which is famous worldwide.
