Four burial chambers are of considerable interest from a decorative point of view. They are indeed large enough to allow both complex decorations in stucco and delicate frescoes following the partitions of the architectural structure.
Tomb III is notable for the quality of its stucco decorations: the ceiling is divided into alternating squares with tondo depicting figures in flight, masks and rosettes; the niches instead depict in relief scenes inspired by Greek mythology, linked to death and the Underworld (Ulysses in Hades, Medea and the daughters of Pelias).
Columbarium II, which was the last to be added to this series of tombs, has one niche larger than the others on the far side, with the vault modelled in stucco in the form of a half shell, a recurrent decorative motif in tombs from this period; the rest of the niche is painted in red and white. The other walls, constructed with niches on two levels, are decorated with frescoes depicting birds, plant shoots and floral motifs.
