Asilah or Arzila (Arabic: أصيلة، أرزيلة; "authentic") is a fortified town on the northwest tip of the Atlantic coast of Morocco, about 31 km from Tangier. Its ramparts and gateworks remain fully intact. Its history dates back to 1500 B.C., when the Phoenicians used it as a base for trade.
The Portuguese conquered the city in 1471, but John III later decided to abandon it because of an economic crisis in 1549.
In 1692, the town was taken by the Moroccans under the leadership of Moulay Ismail. Asilah served then as a base for pirates in the 19th and 20th centuries. http://en.wikipedia.org/wiki/Asilah
