El Cid Campeador is closely related to the region of Castilla-León, where he was born and fought for his king and his country. He is considered a national hero in Spain and monuments and statues have been dedicated to him in several cities in the region, including Burgos, where his grave is located.
In addition, the quartered shield of the Cid Campeador with motifs of castles and a rampant lion, is very similar to the shield of Castilla-León, which reflects the close relationship between this medieval hero and the region in which he was born and fought. El Cid is an iconic figure in Spanish history and Castilla-León in particular, and his legacy lives on in popular culture and in people's memories to this day.
