This article summarizes the archaeological studies carried out in the city of Valdivia between years 2007 and 2012. Different stratigraphic excavations and surface sample collections were conducted under targeted researches and environmental impact studies. Supported by the city's historical chronology, as defined by Gabriel Guarda, 37 sites from different epochs and features have been correlated. The sites' different distributions and types were mapped, referring to the chattel and real property evidence found, construction materials, dating and periods. There is a need to balance the scientific and cultural value of Valdivia's archaeological heritage in future land and urban master plans.
