The Middle Minoan palaces are characteristically aligned with their surrounding topography. The MM palace of Phaistos appears to align with Mount Ida and Knossos is aligned with Mount Juktas, both on a north-south axis. Scholars suggest that the alignment was related to the mountains' ritual significance; a number of peak sanctuaries (spaces for public ritual) have been excavated, including one at Petsofas. These sites have yielded clusters of clay figurines and evidence of animal sacrifice.
