Sancti Petri Castle is an iconic island and castle presiding over the horizon at the mouth of Caño de Sancti Petri. It is accessible by boat, although if you are a water sport enthusiast you may want to contemplate making the trip by kayak. During the autumn or spring equinoxes, mid September or mid March, we recommend that you go to the viewpoint on the beach of Sancti Petri which is one of the seven Magic Points of Chiclana. During these periods the sunset will be directly overhead the Castle known as the temple of Hercules Melkarth and dating from the 15th century. The statue of Hercules points out its location in the sea, and there is a mythical thought that he is buried in the grounds of the castle.
