I hope Gribbin's Stonehenge Geocoin will continue it's travels to historic places in Spain and the Mediterranean; God knows there is enough of them :)
I left the coin at La Casa Derruida (house in ruins) on the small island of Tabarca outside Santa Pola (and Alicante). All though no major historic event has taken place on this island, it is not without interest.
Taken from Wikipedia http://en.wikipedia.org/wiki/Tabarca:
Before 1700, the island was known as Illa de Sant Pau ('Saint Paul's Island') or Illa Plana ('Flat Island'). Believed to be the island that St. Paul disembarked on, the island was a refuge for Barbary pirates up to the end of the 18th century.
Its Tunisian fellow islet off the town of Tabarka was a part of the Republic of Genoa till 1741 when it was conquered by the Bey of Tunis. In 1760, Charles III of Spain ordered the fortification and repopulation of the Spanish island. A group of Genoese sailors shipwrecked near the coast of Tunisia, mostly coming from the islet off Tunisian Tabarka, were rescued and settled here. The islet was renamed Nova Tabarca ("New Tabarca" in both Catalan and Latin). Thus a settlement was created by royal edict on this uninhabited island which the North African corsaries had previously used as a platform for raids on the Levantine coast.
