A reconstruction of the Fogou at Boden, Cornwall, in the early Iron Age. The high angle reveals the extent of the enclosure ditch with internal rampart mound, southern entryway and a 40 meter (gentle sloping southern approach) pathway.
Inside the Fogou, the journey underground begins through the rock cut passage connected to the outer ditch, joining the stone cut steps which lead up to an antechamber (likely covered with a wooden roof, but dismantled in the Romano-British period) before passing through the corbeled passage. The passageway may have been lit with Tallow Candles.
Beyond the antechamber, the stone lined long ‘L Shaped’ fogou corridor, still very obvious to this day, would once have been capped with large stone lintels.
