In 2020, Thomas Romon led a preventive archaeology operation as part of the Mazoulier wind farm project in the commune of Anse-Bertrand. Preventive archaeology involves examining and documenting historical sites before construction begins to ensure cultural heritage is preserved. This particular excavation uncovered some of the earliest colonial structures from the early 18th century in the peripheral overseas territory of the Atlantic coast of northern Grande-Terre. These findings provide insight into the region’s history, tracing its development from that time up to the present day. The site is located in a region that has a complex history, shaped by colonial expansion and the interactions between European settlers and Indigenous populations. The excavation revealed architectural remains and artifacts that help to reconstruct the early colonial period, offering a clearer picture of how the area was settled and developed. These discoveries contribute to a broader understanding of the region’s past and the influences that shaped its present. Romon’s work on this site is part of a larger effort to document and preserve historical evidence before it is lost to modern development. His research has implications for both local and national historical narratives, highlighting the importance of preserving cultural heritage in areas undergoing rapid change. The findings from this excavation will be presented in an upcoming conference, where Romon will share more details about the site and its historical significance. The conference will provide an opportunity for archaeologists, historians, and researchers to discuss the implications of such discoveries. It also underscores the role of preventive archaeology in ensuring that historical knowledge is not lost due to modern infrastructure projects. By examining these sites, researchers can better understand the long-term impact of colonial history on contemporary societies.
