Barcelona Living—Barcelona, Spain
According to legend, Barcelona was founded either by Hercules or Hamilcar Barca, Hannibal’s father, in 3BC. Around 15BC, the Romans took over the town as a castrum, a military defensive position.
In the fifth century, Barcelona was conquered by the Visigoths, and then by the Arabs in 711AD. In 801AD, Charlemagne's son, Louis, reconquered the city and made Barcelona a buffer zone between the Christian kingdoms of the North and the independent Muslim states, which held the rest of the Iberian peninsula until the Treaty of Granada in 1492.
