This historical sign on a rock commemorates an important event. It looks very old and its already half destroyed by nature sun, rain, wind, air in general. You can still read it, though, and learn history while taking a walk among the mountains. This is what it says:
Led by a shepherd 500 Spanish soldiers climbed the east face of the Rock in 1704 from Catalan Bay to surprise the Garrison, but they were discovered and made prisoner. The Shepherds path from near this spot was scarped away soon after.
