Liège, a city rich in history and spirituality, has always been a center of knowledge, where religious traditions, occult practices, and secret societies intertwine. Since the Middle Ages, it has become an influential intellectual hub, home to scholars seeking esoteric knowledge. The city's proximity to Germany and the Netherlands has facilitated the spread of Hermetic, alchemical, and astrological currents.

Jean de Mandeville, a 14th-century explorer and writer, is one of the most enigmatic figures associated with the city. His tales, tinged with symbolism and esotericism, fueled imaginations and influenced the mystical currents of his time. In the 18th century, Freemasonry took root in Liège and attracted many intellectuals fascinated by the quest for knowledge and the transmission of hidden wisdom.

The Saint Paul Cathedral, whose Gothic architecture holds hermetic symbols, is a place rich in spiritual history. The former Saint Denis collegiate church, in the heart of the city, is said to have been the site of practices related to astrology and alchemy in medieval times. The Mount Saint Martin, overlooking the city, is steeped in a mystical past where some pagan traditions are believed to have endured. The medieval underground tunnels and cellars of Liège are also surrounded by legends linked to secret societies and hidden rituals.

Liège was a major center of Freemasonry in Belgium as early as the 18th century. Several lodges were established there, influenced by the Rosicrucian and Illuminist movements circulating at the time. These circles welcomed thinkers engaged in the study of occult sciences and Hermetic philosophy.
