Torre del Serpe
The tower stands south-east of Otranto and is also called the Tower of the Idro. Its construction is thought to date back to Roman times, when it served as a lighthouse fuelled by oil, helping ships pass through the Strait of Otranto. It has a circular base; today only one wall can be admired, as the other has collapsed.
Its name comes from a famous legend about a snake that slipped into the tower and drank the oil from the lamp in order to put it out and shipwreck the Saracens.
