Vestiges gallo-romains d'Andernos-les-Bains, Archaeological site near Saint-Eloi Church, Andernos-les-Bains, France.

The Gallo-Roman vestiges are the remains of a Roman facility with a central building ending in an apse and supported by buttresses. A circular wall encloses the entire site around this structure.

Excavations in 1903 and 1904 in the former cemetery beside Saint-Éloi church uncovered a building of the 4th century shaped like a basilica, with a main nave ending in an apse reinforced by buttresses. The site was classified as a monument historique in 1933.

The site lies in the former cemetery beside Saint-Éloi church, where excavations in 1903 and 1904 uncovered the building. Its plan, a nave flanked by side rooms and ending in an apse, is read as that of a basilica, a form used for public and religious functions in late Roman Gaul.

The foundations lie in the former cemetery just south of Saint-Éloi church, reached on foot from the churchyard. The low walls stand in the open on pale gravel, with a metal railing of horizontal bars crossing the front edge. Nothing shelters the stones, so the light and the weather shape the visit.

The remains show the foundations of a structure that looks like a basilica with side chambers flanking the main nave. This suggests the site may have served a religious or public function in Roman Andernos.
