Vatican Museums

The walls related to "Augusti Augustae Caesares" hold a group of inscriptions commemorating emperors and members of their families (wives and children appointed to the succession). These include not only honorary dedications from influential members of the ruling class, from urban communities and corporations, but also texts commemorating works of various kinds, undertaken or promoted by the emperor himself, relating to public utility infrastructures, such as aqueducts, or the strip along the urban section of the banks of the Tiber. Of particular note are the inscriptions regarding the extension of the pomerium (the sacred boundary of Rome) by Claudius.
Near these walls there is also the altar-ossuary of two knife-makers, decorated with interesting reliefs.
