Situated near the cult site of Delphi and overlooking the Corinthian Gulf from the southern slopes of Mount Parnassus, the site of Kastrouli-Desfina sits at the border of the provinces of Boeotia and Phokis. We are told by Homer (Il. 2.494-759) that the cities in these regions sent ships to fight with the Achaeans at Troy, hinting at a thriving Bronze Age community here. Preliminary work carried out in 2016 and 2017 – which included survey and mapping, along with targeted excavations – has begun to reveal a site fortified with Cyclopean masonry typical of the Late Helladic III period in the region, with the promise of large structures within. Nearby rock-cut chamber tombs with multiple burials – some containing perfume jars and gold foil ornaments – were in use from the Late Helladic IIIA2 to Late Helladic IIIC (Liritzis et al. 2016, Sideris et al. 2017, Chovalopoulou et al. 2017, Levy et al. 2018).
