Sanlúcar de Barrameda is a town founded by ancient Greece, where the historic Tartessos civilization took place. This is where many claim that the mythical Island of Atlantis is buried. A site that the well-known philosopher Plato, a student of Socrates, mentions in his writings and where the oldest Greek divinity of the waters, called God Poseidon, resided and reigned.

In addition, in history, the Guadalquivir river is the strong point and that for centuries gave power to the city. This 657 km long river passes through Seville and through Andalusia. It was the ship road of the ancient civilization, and Sanlúcar was the first and last destination before starting or ending navigation across the Atlantic Ocean. The Vikings were the first to use this natural waterway to rob Seville during the Al-Andalus period under Muslim rule. Then, after the fall of Al-Andalus in January 1492, the invasion of South America began in October 1492 led by Christopher Columbus. The transport of American treasures and goods taken by the Spanish empire for three centuries by the Guadalquivir river, made Sanlúcar one of the richest towns in Spain during this period.

At the end of the 18th century, Sanlúcar de Barrameda was part of the summer residence of the royal family. This made the city a popular summer destination for the upper class, prompting the construction of fabulous Andalusian and other style villas and palaces. These villas give an exclusive image to the city, although today Sanlúcar de Barrameda is one of the humblest towns in Spain.
