The spa is centred on the lake, which is formed by the River La Vée, a tributary of the Mayenne, before it enters a deep gorge cut through the massif of the Andaines Forest.

According to another tale, a very old Franciscan friar who took the waters in Bagnoles found a new astonishing vigour and leapt across the highest rocks above the town, which are still called "Le Saut du Capucin" (The Monk's Leap).

The "Belle Époque" Quarter in Bagnoles-de-l'Orne constitutes a rather well preserved example of what could be classed as a typical early 20th century French bourgeoise residential area.

Similar projects were developed throughout France at the same time, among which are Le Vésinet close to Paris, the Saurupt Park in Nancy and the "Winter Town" of Arcachon.

Built under strict construction regulations and intended for well-off 'curists', that is, those attending the spa facilities, the idea of a residential area right in the heart of the Normandy forest attracted a very wealthy clientele.

Moreover, when it was built, going to thermal pools was not generally popular, but seen, rather, as being associated with elitism, luxury and the aspirations of the privileged social classes, who took pleasure in promoting nature as a place of healing.

The architectural opulence of constructions such as the Villas "Printania", "Le Castel", or the so-called "Swedish Country cottage" as well as the presence of large lavish hotels gives a good idea of the stunning taste of the "Fin de siècle" period.

Probably the most interesting examples of this type of architecture are the "Casino du Lac", built in 1927 by the renowned architect Auguste Bluysen,[5] and the "Saint Jean-Baptiste Church" (1934–1935), which is registered as a listed building.

Both buildings have met the challenge to integrate well with the greenery of the surrounding landscape, while adding a touch of modern design, based on the use of geometric shapes and shades of white.

Lower Normandy, including Bagnoles, was the first region in France, together with Alsace, to change over completely to digital television reception, giving more channels with a higher quality of image and sound to residents.
