On the west coast of the Greek peninsula of Peloponnese, nestled in an impressive lagoon landscape, lies the archaeological site of Kleidi near Samikon. This place has been inhabited since Mycenaean times. Centuries later, an important sanctuary dedicated to the Greek god of the sea, Poseidon, was built near this settlement – the temple was considered the cult centre of the cities of Triphyliens, as this region of the Peloponnese was called in ancient times. This is reported by the ancient geographer Strabo. Under the leadership of the Austrian Archaeological Institute (ÖAI), an international research team followed up on this tradition and, thanks to clear geophysical findings, made a discovery. Excavations brought to light the remains of a monumental temple. Initial dating indicates the 6th century BC. However, many questions remain unanswered. The architectural remains are currently being documented by the international team, and scientists are shedding light on the ancient cult activities, the development of the landscape and the political significance of the sanctuary.

Birgitta Eder is leading the Austrian side of this work. The project reports paint a fascinating picture of the cult site, which the archaeologist traces on the basis of the research findings and the history of the excavations.
