History
Lost in the gentle countryside of southern Touraine, at Marcé-sur-Esves, this vestige of a Gallo-Roman fanum is one of those enigmatic presences that history has left half standing, as if to remind us that memory never quite disappears. This cone-shaped masonry block, made up of regular courses of rubble bonded with a remarkably strong falunière sand mortar, still rises up from the landscape in a sloping silhouette, like a challenge to the centuries. What makes this site truly unique is its very material: this falun-based mortar - the fossilised marine sediment so characteristic of Touraine - betrays the Gallo-Roman builders' detailed knowledge of local resources. The strength of this binder has enabled the block to withstand the ravages of time, where so many other structures have disappeared, absorbed by the earth or dismantled to make way for later constructions. A visit to this archaeological site is a contemplative and learned experience. There are no crowds or illuminated signs here: the silence of the ages dominates, disturbed only by the wind over the fields. Archaeology buffs will read the layers of a complex history - ancient excavations, partial collapses, gradual disappearance of a second block still visible at the beginning of the 20th century. Attentive visitors will notice the southern slope of the cone, probably the result of an earlier excavation that weakened the substructures. The setting of Marcé-sur-Esves adds to the magic of the place. This unassuming village in southern Touraine, nestling between the Esves river and its hedged farmland, retains the atmosphere of a deep-rooted country where ancient times are still visible beneath the ploughed fields. Around the fanum, the rolling, hedged landscape of the Gâtine tourangelle invites you to wander and imagine, far from the beaten tourist track.
Architecture
The Gallo-Roman fanum at Marcé-sur-Esves belongs to the large family of centred-plan sanctuaries characteristic of Roman Gaul. In Latin, the term "fanum" refers to a sacred place, and by extension to these small rural temples, hundreds of examples of which have been identified in France, Belgium and the Rhineland. The typical plan combines a cella (central sacred room housing the divine effigy) with a portico or ambulacrum on the periphery, giving the building its distinctive concentric appearance. What remains today is a cone of masonry made up of regular courses of rubble stone - probably tufa or local limestone - bonded with an exceptionally hard mortar made from falunière sand. This falun, a fossilised marine deposit abundant in the subsoil of Touraine (particularly in the Channay-sur-Lathan and Noyant areas), gave the mortar special hydraulic properties, explaining the remarkable strength of the blocks over the centuries. The dressed facing that originally covered this block has completely disappeared, having been recovered in Late Antiquity or the Middle Ages. The whole structure has tilted to the south, probably as a result of excavations that weakened the foundations. The dimensions of the remains, modest on the scale of an urban temple, correspond to the usual proportions of rural Gallic fana, whose cella rarely exceeded 5 to 8 metres on each side.
