Refers to a natural pagoda, located on the cliff top directly above the Main Western Line, between Tunnels No. 9 and 10. This pagoda has been underpinned by eight brick columns to prevent it collapsing onto the railway line below. Named by Michael Keats on a Bush Club walk, 6th February 2012. Caryatids are sculpted female figures serving as architectural supports taking the place of a column or a pillar. One of the best known examples is a porch annex to the Parthenon on the Acropolis in Athens, Greece.
