Since 2007, a team of the UCLouvain under the auspices of the Belgian School at Athens has been working at Sissi, a Bronze Age or Minoan site on the island of Crete. Apart from a cemetery and an enduring settlement, occupied between 2600 and 1200 BCE, a large monumental complex with central court was also excavated. In this lecture, we concentrate on this building, noting its peculiarities. Moreover, we discuss the various conservation challenges these recently uncovered ruins are exposed to, especially those related to their natural setting, and how these issues have so far been addressed to ensure the long-term safeguarding of the site.
