In 43 BC, the Roman general Lucius Munatius Plancus founded Lugdunum atop Fourvière Hill, deliberately erasing traces of the sacred Gallic sanctuary that once crowned this sacred peak
Dive into the heart of Lugdunum, the ancient capital of Gaul, where the echoes of Roman emperors and Christian martyrs still resonate in Lyon's millennia-old stones.

« Lugdunum, the Augustan colony, was founded in 43 BC on the Fourvière hill. »— Lugdunum Museum Inscription, official historical panel
The story that haunts this land
Your quest begins at Place Bellecour in Lyon, an esplanade created between 1661 and 1671 under Louis XIV by Louis Denis and François de Royers de La Varenne. This 17-hectare square, the second largest in France, is dominated by the equestrian statue of Louis XIV erected in 1825 by François-Frédéric Lemot. From this moment, the city's past, classified as a Historic Monument in 1964, reveals itself, preparing you for the discovery of Lugdunum's foundations extending to the Fourvière hill.
Ascending towards the Fourvière hill, you will reach the Basilica of Notre-Dame de Fourvière. Consecrated in 1896, this Neo-Byzantine basilica, built between 1872 and 1896 with its 50m interior height, has been a Marian sanctuary since 1643. It dominates the historic hill where Lugdunum was founded in 43 BC, as evidenced by the nearby Lugdunum Museum. The vow of the Lyonnais during the Franco-Prussian War of 1870 is inscribed in its 5000 m² of mosaics, and the basilica was classified as a Historic Monument in 2002.
Your journey then leads you to the Amphitheater of the Three Gauls, a Historic Monument since 1840. Built around 15-19 AD under Emperor Augustus, this 103 x 75 m site could accommodate 12,000 spectators and was the site of the martyrdom of Saint Blandina and the first Lyonnais Christians in 177 AD. Lugdunum was then the capital of the Three Gauls, hosting annual assemblies of Gallic delegates from 12 to 260 AD. Archaeological excavations, which began in 1933, continue to reveal the secrets of this major UNESCO World Heritage site from 1998.
The Pointe de la Presqu'île, formed by the confluence of the Rhône and Saône, has been a strategic site since antiquity, directly influencing the establishment of Lugdunum on the Fourvière hill. In the 19th century, major urban development projects shaped its quays and bridges, such as the Pont Bonaparte as early as 1604-1608. This location, classified as a UNESCO World Heritage site in 1998 for the historic city center, allows you to understand the evolution of Lyon, Auvergne-Rhône-Alpes, from its Roman origins to its modern configuration.
Your exploration concludes in front of the Bartholdi Fountain in Place des Terreaux, where the allegory of the Garonne and its tributaries rises 22 m high. Inaugurated in 1892, this work by Frédéric Auguste Bartholdi, the sculptor of the Statue of Liberty, was offered by the city of Lyon to Bordeaux for the 1889 Universal Exhibition before being installed here. Classified as a Historic Monument in 1994, it symbolizes the regional fluvial power. By completing your treasure hunt in Lyon, you carry with you the spirit of Lugdunum, a city that embodies the 'Hope for a better age' ("Auspicium melioris aevi"), and a deep understanding of its history, its monuments, and its role as the Capital of Gaul.
