Archaeologists have discovered a shipwreck graveyard with more than 130 sunken vessels off the coast of southern Spain.

The finds,in the water between the port city of Algeciras and the Rock of Gibraltar span a period from the fifth century BC to World War Two.

Over the centuries,the bay has claimed a wide range of vessels,from Roman ships to more modern British and Spanish ships.

The discoveries form part of a three-year investigation led by the University of Cádiz,which has identified 151 archaeological sites in the bay,including 134 shipwrecks. So far,34 of those wrecks have been documented in detail.
