The tower overlooking the harbour was built in the 16th century as a lookout for Berber pirates. During the day, smoke signals warned other towers along the coast of the pirates' pending arrival, and fires were lit when it was dark.
During October each year, the town holds its moros i cristians (Moors and Christians) festival. The festival includes daily "battles" through the town, where arquebuses are extensively used. There are numerous parades and late night fireworks displays. The evening parades through the centre of the town are resplendent with extravagant costumes.
There are archaeological remains at 'La Isleta', beside the harbour, where circular cabins dating back to 3000 BC have been found. Also known as 'Banyets de la Reina', the he remains of Roman-era fish factories can be seen.
