The
Horrea Galbæ, (Galba Granaries) are huge warehouses built behind
the Æmelius Portico, the slaves of the Emporium used to live there,
and maybe as well imprisoned slaves (ergastuli). They were vast granaries
that belonged during the first century B.C. to the Sulpicii Galbæ family,
the family of the future Emperor Galba. The
tomb of Sulpicius Galba,
consul in 108 B.C., stands close to the warehouses.
