The Torre Flavia *dolia* ship
Between the late 1st century BC and the early 1st century AD, a merchant ship sank off the coast of Ladispoli, carrying huge wine jars, amphorae, and the crew's everyday items. The wreck offers insights into trade, shipbuilding, and life on board.WhereLadispoli waters · shipwreck coordinates not published

THE SITE AT A GLANCE
A terracotta storage vessel inside the ship's hull.
The shipwreck, discovered in 1983 and studied during three campaigns between 1983 and 1985, lies at a depth of approximately twelve meters. The remains were scattered over an area of about four hundred square meters; a section of the hull planking measuring 6.60 by 3.30 meters was preserved. Based on this fragment, scholars have estimated the original length of the ship at approximately 18–20 meters; this is an estimate, not a measurement of the complete hull.
Five large, intact *dolia* and numerous fragments suggest an original cargo of ten to twelve containers, with a total theoretical capacity approaching fifty tons. Resin-lined inner walls and Dressel 2–4 wine amphorae indicate that wine was likely being transported. Stamps linked to the Minturnae area suggest production ties with southern Lazio, though they do not reveal a specific route or the port of destination.
The flat-bottomed hull—built with mortise-and-tenon planking and reinforced in the central section—was designed to carry an exceptional load. However, a sounding weight, wooden bilge-pump discs, sgraffito tableware, a duck-head decoration, and a lidded box interpreted as a medical kit bring the story back to the human scale of those who sailed.
AN ACTUAL ARTIFACT, THE MUSEUM, AND FOUR COMPARISONS
From salt on terracotta to the shape of the ship.
The first photograph is indeed of a *dolium* (large storage jar) recovered from the shipwreck. The other images show the museum, the coastal landscape, or comparative examples; they are never presented as photographs of the underwater excavation itself.
Traces of the sea on the terracotta
Madreporal corals and encrustations mark the surface of one of the *dolia* recovered and preserved at Santa Severa. This is a macro detail of the artifact, not a view of the entire container.

The story continues at Santa Severa.
Within the Castle complex, the Museum of the Sea and Ancient Navigation houses the restored *dolia* (large storage jars) and reconstructs the ship's hold to illustrate the scale and organization of the cargo.

Water outside the bilge
The pump shown in the photograph is an educational replica, not an original part of the ship. However, it helps interpret the perforated wooden discs found on board, which were part of a pumping system.

How the Romans envisioned a merchant ship
The Lod mosaic dates from about three centuries later and does not depict the Ladispoli shipwreck. It merely offers an iconographic comparison regarding the mast, sail, hull, and steering mechanism of a merchant ship.

A vessel larger than a person
The *dolium* in the photograph comes from the Roman villa at Minori, not from the ship. This comparison makes it possible to visualize the shape, thickness, and scale of these large, stationary transport or storage containers.

The tower provides the name, not the coordinates
Torre Flavia defines this coastal area in the public narrative. The photograph does not indicate the shipwreck site and should not be used to search for the wreck.

Restoration and reconstruction of the hold restore the original proportions and functions for the public without exposing the submerged site.
SIX CLUES WITHIN THE SAME SHIP
Cargo and life on board.
The ship carried more than just large vessels. Each group of artifacts sheds light on a different activity, ranging from navigation and maintenance to personal care.
- 01STRUCTURE
Planking and ribs
Planks approximately four centimeters thick, mortise-and-tenon joints, and closely spaced ribs form a sturdy hull, reinforced in the cargo area.
Scientific documentation and museum reconstruction - 02HOLD
Resin-coated and repaired *dolia*
The large jars were integral to the ship's design; their linings and lead clamps provide evidence of their use, maintenance, and economic value.

Confirmed dates, archaeological phases, and traditions are presented for what they truly represent.
- 01
The shipwreck
A cargo ship laden with *dolia* and amphorae was lost off the coast of Ladispoli. Its origin, departure point, and destination remain unknown.

Protecting without pinpointing the location
The shipwreck remains part of the underwater heritage: public knowledge of it is gained through museums and documentary sources, not by independently searching for the sinking site.

WHAT TO OBSERVE
Reading the site,
detail by detail.
Structural containers
These enormous jars were not merely oversized amphorae; their weight and bulk dictated the construction and use of the ship's hold.
A probable load
Internal resin lining and wine amphorae support this interpretation, although no label indicating the original contents has survived.
Mediterranean carpentry
The hull was assembled using mortise-and-tenon joints before the internal structures were installed, following ancient shipbuilding traditions.
Repaired large jars
Lead clamps and pourings indicate that enormous vessels could be repaired rather than replaced.
Technology and daily life
The pump, sounding lead, tableware, and furnishings recreate the crew's daily work, going beyond the mere commercial history.
Viewing without diving
The reconstruction of the hold at Santa Severa makes the *dolia* system visible without endangering the shipwreck.
BEFORE GOING
The shipwreck is best understood in a museum, not by searching for it at sea.
The artifacts and a full-scale reconstruction of the ship's hold section are associated with the Museum of the Sea and Ancient Navigation within the Santa Severa Castle complex on the Via Aurelia. Opening hours, room access, and ticket details may vary depending on the season and current exhibitions.
Always check official channels before setting out. This page does not provide coordinates, alignments, buoy locations, or diving instructions. Do not search for, touch, or retrieve materials from the wreck; underwater archaeology requires permits and specialized preservation.The museum trail displays large *dolia* (storage jars) and shipboard artifacts within the context of ancient seafaring.
The complex operates on a seasonal schedule and is normally closed on Mondays; Check the official website for any changes.
Combined rates, temporary exhibitions, and access to different areas are subject to change: please consult the official ticketing page.
Please check directly before your visit regarding elevators, barrier-free access, facilities, and the availability of the archaeological halls.
