Substantial areas of the ruins have been excavated, including an amphitheatre, a Roman villa, a cemetery, a thermal spring.
One of the rare archaeological testaments of the vergobret comes from the 1978 excavations of Dr. Allain in the zone of the temples to Argentomagus (Saint-Marcel, Indre), where an olla of terra nigra, engraved after being fired, bears the inscription, "vercobretos readdas".
