From the Maritime Executive: Ancient Roman Shipwreck Found in Future Parking Lot Site
A team of Inrap archaeologists is currently excavating part of the
Antique port of Antibes (Alpes-Maritimes). This research, curated by the
State (Drac Provence-Alpes-Côte d’Azur), is being conducted in advance
of the construction of an underground parking lot by QPark. The
archaeologists will work for seven months at the site of "Pré aux
Pêcheurs”.
The Antique Antipolis…
Antibes is the Antique Antipolis, a Greek trading post founded by the
Phocaeans of Massalia. The date of its establishment is still uncertain,
but it followed an indigenous habitat located in the high areas of the
current city. Along the Provençal shoreline, Antipolis occupied an
advantageous location on the maritime routes linking Marseille to the
Italian coast. Like the Saint-Roch cove, it had a natural port that was
protected from the dominant winds. The prosperity of the Greek and then
Roman city was largely based on the dynamic activity of its maritime
commerce, as well as on the transformation of sea products, fish salting
and the fabrication of garum (a fish based sauce).
… and its port
The archaeologists are currently exploring, over 5000 m2, the bottom of
an Antique port basin, which was progressively covered with sand. This
obvious waste dump has yielded many objects – waste thrown from mooring
boats or bits of cargo lost during transshipments – and provides
information on the daily activities of the sailors and the maritime
commerce. The layers of archaeological objects have been accumulating
since the 3rd century BC until the 6th century AD. Several tens of
thousands of objects of all kinds that were sunken underwater in the
Saint-Roch cove have already been recovered, including merchandise
originating from periphery of the Mediterranean basin. They alone
illustrate the dynamic nature of the Antique port and commerce in this
part of the Mediterranean.
The sediments excavated were located under the sea level and were not
dried until the construction of the parking lot. These specific
anaerobic conditions contributed to the preservation of organic
materials and thus allowed the recovery of objects that are not
preserved in excavations on land, including amphora corks, leather shoe
soles and wood objects.
The shipwreck
In the last area explored by the Inrap archaeologists, the wreck of a
Roman vessel was discovered. The boat, preserved over more than 15 m in
length, is lying on its side in a shallow area (less than 1.6 m under
the Antique sea level). In the context of a partnership with the Centre
Camille Jullian, Inrap and a CNRS naval archaeology specialist are
collaborating in the analysis and interpretation of this discovery.
The remains consist of a keel and several boards that covered the hull,
held together by thousands of pegs inserted into sheave slots cut into
the thickness of the boards. Around forty transverse ribs are present,
some of which were attached to the keel with metallic pins.
Elements of the ceiling were also identified. The keelson, which served
to house the foot of the mast, was not preserved. This vessel was a
medium-sized commercial sailboat (20/22 m long, 6/7 m wide, height of
the hold approximately 3 m). Conifer was the main wood used in its
construction. The wood knots of the hull were reinforced by plaques of
lead held in place by small nails. These plaques compensated for the
faults of a medium quality wood, which was used for the construction of
this vessel because is was easily available and accessible. The tool
traces are clearly visible (saw and adze), as is the pitch that was used
to protect the hull. These architectural features support the date
indicated by the stratigraphy and pottery elements recovered in the
levels accumulated after the boat was abandoned – the 2nd and 3rd
centuries AD – and allow the vessel to be attributed to the Imperial
Roman ships of the western Mediterranean.
The cause of its sinking is still unknown. Did it crash against the
shore during a storm? Was it abandoned to rot in a corner of the port?
Was it purposefully sunk to serve as a base for a wharf? These two
latter hypotheses could explain the absence of cargo. The continuing
investigations will surely reveal the answer.
