Greek Cross Hall
The Greek Cross Hall (Sala a Croce Greca) serves as the monumental entrance to the Pio-Clementine Museum, designed under Pope Pius VI in the late 18th century. The hall is named after its architectural plan, which takes the shape of an equilateral Greek cross, a form that conveys a sense of stability and classical order. Flanking the entrance are two colossal Egyptian-style telamones carved from red granite, sourced from Hadrian's Villa. The hall's primary treasures are the two massive red porphyry sarcophagi belonging to Saint Helena, the mother of Constantine the Great, and Constantia, his daughter. These sarcophagi are masterworks of ancient stone carving, featuring complex reliefs of military battles and vintage scenes. The center of the hall's floor is adorned with an impressive ancient mosaic depicting the head of Athena. The combination of rare materials like porphyry and the grand scale of the architecture creates a dignified setting for these imperial funerary monuments.
