cliff-face, which is crowned by a medieval enceinte, is heavily fissured and undermined
by cavities. Various sections of this bedrock had collapsed over time, the
latest incident of which occurred in 2005 (as shown in the accompanying
photographs). A secondary feature of the cliff-face was the use of masonry
revetments which were employed by the Knights to seal off and plug-in various caves
and recesses which were thought at the time to constitute a danger to the
safety of the stronghold. Many of these revetments were found to be partially
collapsed and were in a dire need of repair.
