The sanctuary is in the heart of the Minoan Palace of Knossós. A vestibule, where the British archeologist Evans (1851-1941) placed a porphyry basin, leads into the Throne Room containing a bench and the alabaster throne on which the high Priestess of the Labyrinth sat. Opposite the throne, steps descend to a basin designed for ablutions. Another vestibule leads into the Pillar crypts where the ritual ceremonies took place and into the Treasury beneath which the famous Snake Goddesses were found, now on display in the museum in Herakleion.
