The "Rock" of Gibraltar

 While in Sevilla we took a trip to the Rock of Gibraltar that is at the entrance of the Mediterranean Sea.  Gibraltar is an English territory but is on the peninsula of Spain. Because of its location its been fought over for centuries because in time of war it can control the entry into the Mediterranean Sea.  To get there we had to park on the Spanish side and walk across the international runway that divides Spain from Gibraltar.  The rock has manmade caves that the military used during it's many battles and it has natural caverns.
