An extraordinary heritage legacy linked to Roman culture flanks this historic route between Seville, the southern foothills of the Sierra Morena in Jaén and the ancient ports of Muradal and Montizón. It has been in use since prehistorical times and it was named after Heraclius, also after Hannibal and even misnamed the Via Augusta, and consolidated, with certain variations, with the Bourbon dynasty. Roadways, bridges, castles, inns, hostelries and lodging houses, staging posts and post offices, haciendas, farmhouses, etc. In a word, towns with an immense cultural legacy give shape to a route that is a unique and integral part of the Andalusian idiosyncrasy.
Throughout the Modern Age this roadway, which during the second half of the 18th century and as a result of Bourbon policies became the Royal Roadway of Andalusia, was established as an important axis for agricultural and economic development and the spreading of ideas. The lands that border the road and river are dotted with haciendas and farmhouses, and extensive agricultural complexes that supplied the Galleons and Fleets bound for the Indies with food. Even though farms producing olive oil occupied the greatest extension of land, they were not alone as there was truly diverse trade in oils, wines, cereals, blankets, etc.
It is traditionally known as the "Vía Augusta", although it would be more correct to call it Roman Road "A Gadibus Romam". In Roman times it connected Gades with the Upper Guadalquivir region and the eastern peninsular after passing through the Sierra Morena. It joined the fertile plain of Seville to that of Córdoba through the green fields of Carmona and Écija, continuing as far as Cástulo (Linares), Andújar and Mengíbar (Iliturgi). At this point, the road forks and there are several alternatives which could be considered as different extensions until they reach the mountains, either to access the Plateau via Despeñaperros and the Muradal mountain pass (Road from Toledo to Granada), or Eastern Spain through the town of Montizón.
