The Great Warehouse
(Reg. II. Is. IX, 7)
Ostia's largest commercial building is traditionally dated to the period of the emperor Claudius (AD 41-54), though recent studies have proposed an initial date in the 1st century BC. It had a porticoed courtyard with tufa columns (B), around which the cellae (storage rooms) (C) were arranged on three sides. It was completely rebuilt between the late 2nd century and the early 3rd century AD, when the brick walls were renovated, two parallel rows of cellae were added in the centre of the courtyard and the second storey was built. At this time, the floors of all the cellae were raised using suspensurae (little brick pillars), thus creating a space that insulated the grain stored here from damp.

Excerpt: "The poor state of preservation of the Great Warehouse is in sharp contrast with its importance. Many of the large tufa blocks from the outer west and east wall were reused in the Casone del Sale - the present museum - built in the second half of the 16th century. Two lime-kilns were found in the building. The east facade was unearthed by Rodolfo Lanciani in 1885-1886, most of the building was excavated by Guido Calza at the end of the First World War."(Submitted on August 11, 2025, by Sean P.
