The article analyzes cultural evidence found at La Capilla cave to learn about the social interactions that occurred there. The analysis is undertaken from the lens of social archaeology, taking into account that the site is a unique place in Chile's northern coast. The site yielded pictorial evidence and cultural remains in an environment associated with fishing settlements of the Late Archaic Period (1800-800 BC). The discussion revolves around the importance of the cave, which seems to have been built by fishermen as a monument with a variety of social functions.
