Álvaro de Bazán el Viejo

Don Álvaro de Bazán, called the Elder (1506–1558) was a Spanish naval commander from an old Navarrese noble family who received several nobilary titles such as the rank of Admiral of Castile, Marquis del Viso, and General-Captain of the Galleys of Spain. He was the father of Álvaro de Bazán, 1st Marquis of Santa Cruz, who surpassed him in fame. At the age of eight his son was appointed "Military Governor and captain of the fortress and city of Gibraltar". His command however was via his father. It has been speculated that this unusual appointment was intended to show Charles V's confidence but Bazán the Elder did not share that confidence and he suggested to no effect that Gibraltar's Line Wall Curtain be extended to the southern tip of the rock.
