One of the city's notable features during antiquity was the temple on the south end of its island dedicated to the Phoenician god Melqart, who was conflated with Hercules by the Greeks and Romans under the names "Tyrian Hercules" and "Hercules Gaditanus". It had an oracle and was famed for its wealth. In Greek mythology, Hercules was sometimes credited with founding "Gadeira" after performing his tenth labor, the slaying of Geryon, a monster with three heads and torsos joined to a single pair of legs. (A tumulus near Gadeira was associated with Geryon's final resting-place.) According to the "Life of Apollonius of Tyana", the "Heracleum" (i.e., the temple of Melqart) was still standing during the 1st century. Some historians, based in part on this source, believe that the columns of this temple were the origin of the myth of the "pillars of Hercules".
