A remarkable archaeological study has uncovered the ruins of a 1889 tourist hotel that once stood proudly on the Atlantic coast of Argentina but has since been entirely buried by shifting sand dunes. This significant finding was made by documentary filmmaker Laureano Clavero and architect Pablo Grigera, shedding light on the legacy and history of this pioneering structure which has largely faded into legend over the years. The Hotel Mar del Sud was situated in an untouched area of fields and beaches, specifically in the region known today as El Remanso, approximately two kilometers from the only paved road in the locality. It is a part of the village of Mar del Sud, a place known for its contrasting stories and bold projects. Traditionally, the local narrative has focused on the Boulevard Atlántico, but this archaeological discovery brings to light an earlier architectural accomplishment that played a role in the area’s development. This find has wider implications for heritage tourism in Argentina, as it highlights the importance of preserving and recognizing historical structures that tell the story of development along the coast. The hotel, a symbol of a bygone era in Argentine tourism, presents an opportunity for further exploration into the region's past and how it has been shaped by natural forces over time, emphasizing the need for a balance between nature and history in coastal areas.
