Cadiz, Known as Didymé by the Greeks

In ancient times, Cadiz, or Didymé as the Greeks called it, was an island. According to authors such as Pomponio Mela and Plinio the Elder, this city was an island, a fact that still holds true today, though it may not be immediately apparent. Cadiz had two urban centers, one on the islets and another on the mainland. The name Didymé (in ancient Greek, didymé, meaning 'twin') refers to these two urban centers.
