Between the coastal lagoon called MarMenor and Cartagena is Cabo de Palos. Atop the highest point on the cape is a former watchtower that is now a lighthouse. During the early nineteenth century, it was part of a chain of watch and signal towers built to warn of the approach of the Barberry pirates.

AtCabo de Palos, the light
That aids ship navigation by night
Was once a watchtower
Against pirate power
To protect against Barberry might.
