Abstract

In this work, we present results of the first geophysical studies carried out at the historical site Vuelta de Obligado, where in 1845 the well-known battle took place between troops of the Argentine Confederation and an alliance between France and England, which sought to control the navigation of the South American rivers with the aim of imposing free trade. The main objective of the studies carried out so far has been to explore different sectors of the site in search of remnants of historical structures such as basements, trenches, embankments, burials, etc.
