Portico of the Aetolians and Delphi refer to what culture?
Portico of the Aetolians The Portico of the Aetolians, known also as the Western Portico, is one of the largest buildings of Delphi, situated outside of the sacred precinct of the sanctuary of Apollo.
Kastri culture The Kastri culture (Greek: Καστρί ) refers to a "cultural" dating system used for the Cycladic culture that flourished during the early Bronze Age in Greece. It spans the period ca. 2500–2200 BC and was named by Colin Renfrew, after the fortified settlement of Kastri near Chalandriani on the Cycladic island of Syros. In Renfrew's system, Kastri culture follows the Keros-Syros culture. However, some archaeologists believe that the Keros-Syros and Kastri cultures belong to the same phase. Others describe this period as the "Early Cycladic III (ECIII)".
