project director: Dr. Jan Szymański
research location: San Isidro archaeological site, department of Sonsonate, El Salvador, Central America
site characteristics: The site has been continuously eroded by heavy agricultural machinery. Currently ca. 20 visible remains of monumental architecture are still recognisable. Dating of surface collections of pottery encompasses the Middle (ca. 1000-400 BC) and Late (ca. 400 BC-AD 250) Preclassic periods. San Isidro most likely served as a large regional center at the southeastern frontier of the Pre-Columbian Maya culture. The reconnaissance works were carried out between 2018 and 2020. In 2021 archaeological excavations commenced.
