Pessegueiro Island - Portugal

This is a card from my portuguese wishlist, Pessegueiro Fortress on Pessegueiro Island and it was sent by Ana "ninocas".

"Pessegueiro Island is located on the coast of Alentejo Litoral, in the Municipality of Sines. It's a small island near Porto Covo, a small town with a famous beach. The island and the adjacent coast are part of Southwest Alentejo and Vicentine Coast Natural Park.
The island has a history of occupation going back to the Carthaginians. At the time of Roman conquest of Hispania, the island hosted a small fish processing centre, as evidenced by recently discovered remains of salt tanks. To help defend against privateers, the natural anchorage was extended at the time of the Iberian Union with an artificial rock barrier connecting the island of Pessegueiro to the coastline.
In 1590 began the construction of the Pessegueiro Fortress. The fort occupied a dominant position on the island, with the purpose of providing military support to another fortress on the mainland." - in: wikipedia
