The Viper’s Cave (La Grotta della Vipera) name comes from the emblem of two crossed snakes carved on the front of the cave. The temple-shaped monument is carved into a rock and was dedicated to a Roman matron named Atilia Pomptilla. This is where she prayed to the Gods to let her die instead of her husband Cassio Filippo, who was exiled in Sardinia by Nerone. This important Roman funeral monument dates from the end of the 1st Century B.C. to the beginning of the 1st Century AD and can be found at the foot of the Tuxiveddu hill.
