Archeological sites protected by the law

Wrecks and objects lying on the seabed are considered to be cultural property. This is why they are protected by law, and deemed to be the property of the French State.

Diving prohibited at historical sites

It is against the law to dive at the sites of ancient shipwrecks. On the one hand, this avoids unscrupulous divers plundering the site, whether to resell an object or merely to keep it as a souvenir of their dive, and on the other hand, this also avoids anyone disturbing the site's archaeological setting.

Excavation of the ZI 24 wreck

The ZI 24 wreck (which stands for "exclusion zone 24" in French) was discovered in 1989. It was surveyed in 2011 and excavated in 2012 by ADRAMAR.

The wreckage was named ZI 24 because it is located close to buoy 24, which marks out the exclusion zone around the La Rance tidal power station, which generates electricity using energy from the tides. This makes diving procedures for the site more complex

A wreck dating from the 17th and 18th centuries

Eleven cast-iron cannons, laid out nose to tail and side by side, have been studied. These are not part of a battery of artillery, but were used as ballast for the ship. The remains of the hull can be found underneath the cannons.

For now, wreck ZI 24 remains a mystery, with no sign of any formal identification, despite the field and archive research carried out.

A recreated archeological site?

In order to allow everyone to dive down to experience an archaeological site, ADRAMAR has installed a recreation of an archeological site at the foot of La Rance de Bizeux. The site of wreckage ZI 24 served as a model for the creation.

Bizeux Rock

Located in the estuary of La Rance, the Bizeux site is ideal for diving, with its location sheltered from the ocean swell.

Genuine artifacts re-submerged

Genuine cast-iron cannons and a giant anchor have been made available and studied by ADRAMAR for this project. These objects were discovered on sites off the coast of Saint-Malo, but hadn't found a place in museums. So, they were re-submerged.

Recreation of a shipwreck site

The Bizeux archeological recreation site reproduces all the elements of an 18th-century shipwreck before archeological investigations.

Two cannons, fitted as ballast to weigh down the ship, have found a bed among the stone ballast. Marking the axis of the ship's keel, they are implanted in the same way as those which were discovered a few hundred meters away on the ZI 24 wreck.

Three cannons are located on the flank of the wreckage. They were in defensive battery positions at the sides of the ship.

Here, you're the archaeologist!

The re-submerged remains allow you to explore a shipwreck, just like an underwater archaeologist would.

Marked out by a buoy, the site can be accessed by snorkeling when tides are low in high coefficients.

Dive (quite literally) into archeology

The Bizeux site can give you not just one, but two firsts: discovering diving and discovering underwater archeology.

As close to the remains as you can get

The benefit of a recreated site lies in the option to explore it without the restrictions and constraints of an archeological site.
