Valencia, Spain

Valencia is located in the middle of Europe's most densely developed agricultural region. Originally a Greek settlement, the town was taken over by Romans in 138 BC and turned into a retirement town for old soldiers. The Moors controlled the land for 500 years, and this fertile plain, which today yields three to four crops, was considered to be heaven on earth. El Cid conquered Valencia for Spain in 1094, but it fell back into Moorish hands after his death. Incorporated into Spain in the 15th century, Valencia remains the nation's breadbasket.
