"It was built in the third century by a well-off couple in memory of their two sons. The couple might have run both an agricultural estate and the region's mines. Tombs of such opulence are rare, and in France only one other example is known, at St-Rémy-de-Provence. Its half-buried position is due to the accumulation of matter brought by runoff (the monument was cleared several times in the 19th century). The main room probably housed the sarcophagi and statues of the deceased. The building is constructed from large carved blocks of limestone laid very evenly, and its entrance is topped by an archivolt (ornamental side of a stone arch) decorated with scrollwork (coiled plant motifs) and a lintel.” (A. Boemare)
