The remains of a coastal settlement were found at Boucan-Canot, on Cap Champagne hill, in Cap de La Houssaye.

One of the first properties on the island

In 1668, the Compagnie des Indes orientales awarded a concession  to the settler Gilles Launay which corresponds to the location of these remains on Cap Champagne. He built a habitation where he bred livestock. The built remains in Area 2 include quadrangular structures, building foundations and a section of perimeter walls.

Launay’s heirs, the Aubert family, are thought to have sold their home in the 18th century to the government, which built a lookout on the site.

Remains of a lookout

The lookout posts set up around the coast from the 18th century were designed to give advance warning of an attack from the sea. The lookout on Cap de La Houssaye was built between 1793 and 1796. It was composed of a large house with a kitchen and a signal mast. Archaeological research – surveys in 2015 and test pits in 2016 – concentrated on one section of these remains and revealed evidence of this habitation. The finds are typical of 18th and early 19th century domestic life.
