The bustling resort of Alicante serves not only as the port for Madrid, but is also one of the loveliest vacation spots along Spain's sunny Costa Blanca. The latter is primarily due to the pleasant climate. Various civilizations have flourished along these shores. Early records indicate that the city dates back to a Carthaginian settlement established in 325 BC. These settlers were followed by the Romans, who equally found the area inviting. Then the Moors ruled this region for five centuries and named the city Al-Akant. Today's name probably stems from this origin. The city's occupation by Roman and Moorish forces accounts for a notable and varied heritage. In fact, much of this cultural impact is still apparent today in numerous buildings, names and the cuisine.
