The building was never a temple dedicated to the goddess Diana, a name attributed by local lore during the Middle Ages.
Archaeological evidence suggests the roof was constructed using a self-supporting barrel vault made of massive limestone blocks, a notable engineering feat for the period.
The interior walls contain niches designed to house ornamental statues or busts, characteristic of decorative Roman public spaces.
During the Middle Ages, the structure was repurposed as a chapel for the Abbey of Saint-Sernin, which helped preserve its remaining walls.
The monument is built directly against the slope of Mont Cavalier, integrating the natural hillside into its architectural layout.
The Temple of Diana is a first-century Roman structure situated within the Jardin de la Fontaine in Nîmes, France. Despite its name, the building's original function remains a subject of archaeological debate, with theories ranging from a sanctuary dedicated to imperial cults to a public library or nymphaeum. It features distinct barrel-vaulted stone roofing and surviving niches that once held statues. The structure was significantly damaged during the Wars of Religion in the 16th century when it was set on fire. It remains one of the most prominent Roman ruins in the city, showcasing sophisticated Roman masonry techniques. The site is currently an open-air ruin maintained as part of the public park's archaeological circuit.
