Hi
The whole area is fenced and out of bounds so I doubt that there is any intent to preserve it. A hang out for various levels of society best not even imagined. Hate to be there on a summer evening about 2am.
The concrete they poured down the cliff face is quite degraded. It looks like there was some efforts to demolish some of it. All the low areas in the different terraced positions and rooms were full of ice. You could see where it swelled and froze and thawed and froze etc. The blow there and the ocean swell is impressive. Very destructive too, I suppose. If there is no plan to preserve the site then those guns will just tip into the sea some day.
regards
Darrell
