Puesto Arbilla
,
The Arbilla Post is a sector of the La Florida estate located in the valley of Laguna del Desierto where the homonymous outpost of Carabineros de Chile was established, belonging to the Lago O'Higgins detachment. On November 6, 1965, Lieutenant Hernán Merino Correa died in a clash with the Argentine National Gendarmerie during the Laguna del Desierto dispute between the two countries.
Currently, near the location of the events, there is a place called "Sovereignty Square" with signs recounting the events.
