Tizona (also Tizón) is the name of one of the swords carried by Rodrigo Díaz de Vivar, El Cid, according to the Cantar de Mio Cid. The name of the second sword of El Cid is Colada.
A sword identified as Tizona was given by Ferdinand II of Aragon to Pedro de Peralta, count of Santisteban de Lerín in c. 1470. This sword was long kept in Marcilla Castle, later in the Army Museum in Madrid and since 2007 in the Museo de Burgos.
