has also been identified as the site of the legendary Ars Gerionis, the tomb of Geryon, which stood at the end of a narrow cape that jutted into the sea, probably in what is now a reef known as the Stone of Salmedina, near Salmedina, or just Salmedina. These claims are based solely on the evidence of the literature and Roman archaeological findings dating from the second century B.C. Middle Ages Legend relates that the disciples of St. Augustine in Africa, fleeing the invasion of the Vandals, came by sea to Chipiona with the image of the Virgin of Regla. Tombstones have been found near the Shrine of Our Lady of Regla from the time of the Visigoths. After the islamization of the Iberian Peninsula in 711, according to tradition, the hermits hid the image in a cistern about thirty paces from the citadel, now a monastery. The picture remained hidden in a religious of the Order of St. Augustine until it was found in the 14th century, according to legend, following a revelation from heaven. A Shrine to Our Lady of Regla was built around the cistern. In 1251 Chipiona was conquered by King Ferdinand III, and again more definitively in 1264 by his son Alfonso X the Wise. In 1297 King Ferdinand IV granted Guzman el Bueno, founder of the House of Medina Sidonia, the Lordship of Sanlúcar, to which Chipiona belonged. In 1303 the eldest daughter of Guzman el Bueno and Maria Alonso Coronel, Isabel Perez de Guzman, Fernan married Ponce de León, receiving as a dowry the towns of Rota and Chipiona, thereby becoming independent both of the Lordship of Sanlúcar and joining the possessions of the Ponce de León family, germ Arcos House. Modern Age In 1755, Chipiona was severely hit by the tsunami that was caused by the Andalusian and Portuguese Atlantic coast Lisbon earthquake. The effects of the tsunami came to town about an hour after the earthquake, killing four people and leaving flooded streets and beaches, estimating the actual damage to 238 815. He pulled in procession the image of Christ of Mercy to request the withdrawal of the waters, procession that is repeated every year on November, from the chapel that bears the name of Christ to the Cross the Sea.
