The Horrea Galbae were warehouses (horrea) in the southern part of ancient Rome, located between the southern end of the Aventine Hill and the waste dump of Monte Testaccio. They ran for a substantial distance, possibly extending as far as the Porta Ostensis in the east and the Porticus Aemilia on the banks of the Tiber. The horrea were probably built on the site of a suburban villa owned by the Sulpicii Galbae, a distinguished noble family of whom the 1st century AD Roman Emperor Galba was a member. (There are many alternative spellings of the name: Galbana, Galbiana, Galbes and so on.)
